What are Numbers?

Within our everyday routines, we use numerals. They are frequently referred to as numbers.

We can’t count objects, calendars, age, cash, or anything else without numerals. These digits are often used for measuring and several other situations for labeling.

Numbers have features that allow them to conduct numerical calculations on them.

These figures are given both numerically and in utterances. For instance, 4 is written as four, 98 is written as ninety-eight, and so on.

To understand further, students must learn how to write the numerals from 1 to 100 in syllables and by spelling.

There are several sorts of numbers that we study in Mathematics. Natural and whole numerals, odd and even numerals, rational and irrational numerals, etc., are all examples.

In this post, we’ll go through all of the various sorts. Aside from that, numbers are utilized in a variety of industries, including sequence, arithmetic formulas, and so on.

Types of Numbers

The number system is a way of categorizing numerals into groups. In math, there are several distinct sorts of numbers:

Natural Numerals: Natural numbers are accounting numbers made up of positive numerals ranging from 1 until ∞. The group containing natural numbers is symbolized by the letter “N,” and it consists of N = 6,7,8,9…….

Whole Numerals: Whole numbers are non-negative numbers that have no fractional or decimal components. It is represented by the letter “W,” and the group of whole numbers contains W = 0, 1, 2, 3, 4, 5,………..

Integers: The collection of all whole numerals, as well as a negative group of natural numerals, is known as integers. Integers are represented by the letter “Z,” and the group of integers can be represented as Z = -2,-1,0,1,2.

Real Numbers: Real numbers are all positive and negative numerals, fractions, and decimal values that do not contain imaginary values. The letter “R” is used to signify it.

Rational Numbers: Rational numbers are any numerals that may be represented as a relation of one value to another value. Any integer that may be expressed in terms of p/q complies with the requirement to be a rational number. The rational number is represented by the letter “Q.”

Irrational Numbers: Irrational numbers are those which can be stated as a proportion of one to another and are denoted by the letter “P.”

Complex Numbers: Complex numbers “C” are values that may be represented as a+bi, in which “both a,b” are real values and “i” is an arbitrary value.

Imaginary Numbers: Imaginary numbers are complex numbers that may be expressed as a combination of a real value and the imaginary component “I.”

Whole number All natural numbers including zero are called whole numbers.
Properties of whole number:-

Addition– closure property- the sum of whole numbers is always a whole number.
Commutative property- a+b = b+a
Associative property- (a+b)+c = a+(b+c)
Identity element- if zero is added to any whole number the sum is the number itself.
0+a = a+0 = a
subtraction – closure property- the difference of two whole numbers is not necessary a whole number a-b ≠ b-a not necessary a whole number.
Commutative property a-b ≠ b-a is not defined.
12-4 ≠ 4-12 is not defined.
Property of zero- 0-a ≠ 0-b is not defined.
Associative property- (a-b)-c ≠ a-(b-c)

Division– Dividend- the number which is to be divided is called a dividend.
Divisor– the number by which dividend is divided is called the divisor.
Quotient– the number of times the divisor is contained in the dividend is called the quotient.
Reminder– the leftover number after division is called the reminder.
Thus, the relationship between these terms.

Fractions The numbers in the form of a/b where a and b are whole numbers and

Rational numbers The numbers in the form of a/b a where a and b are integers.
Fractions are also rational numbers a is called the numerator and b is called denominator
equivalent rational number .

Relational numbers between two relational numbers

If given two relational numbers are a and b then is relational number between a and b.
Example
and

More that one relational numbers between two rational numbers
Write and rational numbers between and
Convert two given rational number into equivalent form with common denominator

To obtain 4 Relational numbers between them multiply numerator and denominators with (4+1=5) to make equivalent relational numbers(Multiply n+1 times where n is required number of relational number between two relational number)

and
then
and

where the denominator of Relational numbers is greater.

Relational numbers multiplication

Relational numbers division

Factor– A factor of a number is an exact divisor of the number. Itself in other word the number that are multiplied to get a product are called the factor . for e.g.- 1,2,3,4,6&12 are the factors of 12.
Multiple- a multiple of a number is a number obtained by multiplying it by a natural number. If we multiply 4 by 1,2,3 we get 4,8, 12 which we all multiple of 4.

Even number– A natural number which is exactly divided by 2 is called an even number.
Odd number– A natural number which is not exactly divisible by 2 is called an odd number.
Prime number– A natural number which is greater than 1 & whose only factors are 1 and the number itself is a prime number.
Composite number– The number having more than two factors are called composite numbers.
Co-prime numbers– The two numbers which has no common factor other than one are called co-prime number (2,3) (3,4)

Further research into numbers shows that some more numerals exist in addition to the ones listed previously, such as even and odd digits, prime numerals, and composite numerals. They are discussed below:

• Even Numbers: Even numbers are numerical values that are perfectly divisible by two. Positive or negative numbers, like -92,-38,6,18,24, 28, etc., are some examples of even numbers.
• Odd Numbers: Odd numbers are numerical values that are not perfectly divisible by two. Positive and negative numbers, like -1,-17,13,15,21,23, are some of the examples of odd numbers.
• Prime Numbers: The numerals with only two factors are known as prime numerals. 1 and the digit itself, to be precise. In other terms, prime numbers are the result of dividing a value by one and the value itself. 13,19,53,61,89 are all prime numbers within 100 number.
• Composite Numerals: A composite value consists of 3 or more factors. For instance, the value 15 is a composite number since it is divisible by 1,3,5 and 15. 44,66,91,82,36 are some of the composite numbers under 100 digit value.

There are some special numbers in mathematics as well,

Cardinal Numbers: A cardinal value means the number of units in a sequence, like fifty, thirteen,sixty, seventy, etc., are some of the examples of cardinal values under 100 digit value.

Ordinal Numbers: To describe the place of anything in a list, we use ordinal numbers. For example, 20th will be written as twentieth.

Nominal Numbers: The term “nominal number” refers to a number that is solely referred to as a name. It has no bearing on a thing’s real value or placement.

Pi: Pi is a unique number that is roughly equivalent to 3.14. The proportion of the circumference of a circle reduced by the diameter of a circle is known as Pi ().

Circumference/Diameter = 3.14.

Euler’s Number (e): Euler’s number is roughly equivalent to 2.71, and it is among the most important metrics in mathematics. It is the root of the natural log and is an irrational numeral.

Golden Ratio: The golden ratio is really a unique number that is roughly equivalent to 1.618. It’s an irrational numerical with no discernible pattern among the numbers.

Various properties of numbers

For real values, the characteristics of numbers are mentioned clearly. The following are some of the shared properties:

Commutative Property: If a and b represent two actual values, then the commutative principle states that their sum or multiplication is equal.

a + b = b+a

b.a = a.b

4+5 = 5+4 and 4.5 = 5.4 are two examples.

Associative Property: If a, b, and c represent three real values, then the associative principle states that

(a+b)+c = a+(b+c)

(a.b).c is the same as a.(b.c)

(4+5)+6 = 4+(5+6), (4.5).6=4.(5.6) are two examples

Distributive Property:If a, b, and c represent 3 real values, then the distributive principle states that a

a*(b+c)=a*c+a*c

We can verify the above principle as,

4*(5+6)=4*5+4*6

4*11=20+24

44=44

L.H.S=R.H.S

Closure Property: If one value is added to some other, the output is a single number, as in a+b = c, where a, b, and c represent 3 real values.

5+6=11 is an example.

Identity Property:The identity property states that if we multiply a number by one or we add zero with it, the result will be the same.

x+0= x

x.1=x

7+0 Equals 7 and 7 x 1 = 7 are two examples.

When a positive number is added by the negative value, the outcome is zero.

0 = x+(-x)

5+(-5) = 5-5 = 0 as an example

Inverse Multiplication: When a number other than 0 is multiplied by its own reciprocal, the outcome is 1.

1 = x * (1/x)

50 x (1/50) = 1 as an example

Property of Zero Product: When x.y = 0, either x or b must be 0.

For instance, 9 x 0 = 0 as well as 0 x 10 = 0

Reflexive Property: The value mirrors the digit itself.

x=1

12=12 is an example.

Indian Numeral System

Consider integer 111 as an example. It’s worth noting that the digit 1 appears thrice in this integer. They each have a distinct worth. We distinguish them by mentioning their positioned value, which can be specified as a digit’s numerical value based on its location in a number. As a result, the leftmost one has a place value of hundreds, whereas the one in the middle has a place value of tens, and the one on the right side has a place value of ones.

Returning to the Indian numeral concept, digits have place values of Ones, Tens, Hundreds, Thousands, Ten Thousand, Lakhs, Ten Lakhs, Crores, etc.

The positional meanings of each digit in the integer 12,48,94,231 are:

• 1 – Ones
• 3 – Tens
• 2 – Hundreds
• 4 – Thousands
• 9 – Ten Thousand
• 8 – Lakhs
• 4 – Ten Lakhs
• 2 – Crores
• 1 – Ten Crores

International Numeral System

As in international numeral standard, digit place values are assigned to Ones, Tens, Hundreds, Thousands, Ten Thousand, Hundred Thousands, Millions, Ten Million, and so on. The position values of every digit in the number 30,264,019 are:

• 9– Ones
• 1– Tens
• 0 – Hundreds
• 4 – Thousands
• 6 – Ten Thousand
• 2 – Hundred Thousands
• 0 – Millions
• 3 – Ten Million

How was Zero Number discovered?

0 (zero) is an integer as well as a numeric value used to depict it in numbers. Zero is a number that denotes the lack of all other numbers. It is the identity component of fractions, real values, and several other arithmetic frameworks and hence plays a crucial role in maths. In position value systems, zero is often used as a temporary replacement, just like a digit.

Aryabhata was a famous Mathematician-Astronomer during the ancient period. He is recognized as one of the finest mathematicians of all periods, having been born in Pataliputra, Magadha. Aryabhata became eternal after giving the public the numeral “0” (zero). The Aryabhatiya, his treatise, contained astronomical and mathematical ideas in which the Globe was assumed to be rotating on its axis, and the planets’ cycles were calculated in relation to the rotation of the sun.

The guidelines for working with integer zero are as follows. Unless otherwise indicated, these laws apply to any complex number x.

• Multiplication: a + 0 = 0 + a = a (In other words, when it comes to addition, 0 is the identity component.)
• Subtraction rules: a-0 = a and 0-a = -a.
• Multiplication: a.0=0.a=0
• Division: For nonzero a, divide by 0 / a = 0. However, a/ 0 is undefined since, as a result of the preceding criterion, 0 doesn’t have a multiplicative inverse. For positive a the quotient rises toward positive infinity as b in a / b tends to zero from positive numbers, while when b tends to zero with negative numbers, the quotient rises toward -∞. Division with zero is indeterminate, as evidenced by the various quotients. Exponentiation: a.0 = 1, with the exception that in rare cases, the condition a = 0 may indeed be left undetermined. 0.a Equals 0 for any positive number a.
• Note:The multiplication of 0 integers equals 1, while the total of 0 numbers equals 0.

Here are the Names spellings of numbers from 1 to 100

Why is it important to name the number’s?

Each student must be familiar with the titles of the numerals. These are essential math skills that will assist children inappropriately spelling numbers. They can also readily write such values when they participate in lessons, and their professors spell them out.

In math’s, integers are extremely important. These numbers provide the foundation for all algebraic and numeric processes, not just in basic school but also in secondary ed.

How can I learn Number Names from 1 to 100 Easily?

All you have to do is assist your children in memorizing the digits up to 20, and then a sequence is established from Thirty to 100, as shown below:

Properties of Whole Numbers:

•The digit 0 is the lowest, and initializing whole numbers, as well as all-natural numbers, including zero, are referred to as whole numbers.

• There is no such thing as a culminating or biggest whole number.

• Because whole numerals are indefinite, there is no greatest whole numeral.

• There is an unlimited amount or an unimaginable range of whole numerals.

• Every Natural Number is a whole numeral.

• Each digit is one higher than the one before it.

• Each Whole number is not a Natural number.

1 billion in rupees: Billion to Lakhs Crores Million

If we talk about the Indian currency i.e. Rupees, then 1 billion is equal to 10000 lacs.

1 billion is equal to 10000000000 which is a natural number.

The number 1000000001 comes after 1 billion and the number 999999999 comes before it.

To describe in quantities in Math, the concept of place value is used. Primarily, there are two methods that are used extensively for interpreting the place value of the digits in a particular number.

These two methods are the international number system and the Indian number system.

The positional value of a number is determined by using the place value charts.

Numbers in the general form can be extended with the support of positions.

We start ordering the place value from the right direction to the left direction.

The value of place progresses to tens, hundreds, thousands, and many more starting with the unit location i.e. one’s place.

Continue reading to find out the value of 1 billion dollars in rupees in words and the value of 1 billion in rupees of the Indian number system of place value.

We will also describe to you the position value charge for both the international number system and the Indian number system.

The Place Value Charts for the Indian Number System

The position value sequence in the Indian number system is as follows

1. Ones – 1
2. Tens – 10
3. Hundreds – 100
4. Thousands – 1000
5. Ten Thousands – 10000
6. One Lakh – 100000
7. Ten Lakhs – 1000000
8. One Crores – 10000000
9. Ten Crores – 100000000

The Indian number system is also known as the Hindu-Arabic number system.

You can also use a comma between the zeroes to differentiate between the intervals of this numbering scheme.

Here is a basic rule that you need to follow if you wish to use commas between zeros in the Indian number system – The 1st comma will come after three digits from the right and followed by two digits, then followed by two digits, and after that followed by every two digits.

What essentially means converting billions to rupees?

The place value of digits is referred to in several ways in the international number system and Indian number system.

The digits in the Indian system have place values such as ones, 10s, hundreds, 1000s, 10000s, lacs, 10 lacs, crores, 10 crores, and the sequence goes on in the following manner.

On the other hand, the digits have position values such as ones, tens, hundreds, thousands, ten thousands, hundred thousands, 1 million, 10 million, 100 million, 1 billion, 10 billion,  100 billion, and the sequence goes on in the same manner in the International Number System.

Here’s a quickie – One billion is equal to one hundred crores in the Indian National Rupees.

1000000000 Indian Rupees = 1 Billion

It is also equivalent to ten thousand lakhs (or 10000 lakhs) as one lakh holds the value of 100000 Indian Rupees.

Therefore, one billion is equal to one hundred crores (or 100 crores).

How can you use the calculator for the conversion of billion to rupees?

A person can use the following rules for the conversion of billion to rupees –

1. First of all, you are required to type the desired number of billions in the given input space.
2. Tap on the ‘Convert’ button to get the conversion value.
3. The conversion value from billions to rupees will be shown in the output region.

The above-mentioned 3 simple steps are the key for converting your desired billion number value to Indian National Rupees in a matter of few seconds.

Conversion From Billion to Lakhs

If you wish to convert billions to lakhs, then you should multiply the given billion value by 10000 lacs to get the result.

For example, if you want to convert 7 billion to lacs, then you should multiply 7 by 10000 lakhs.

10,000 lacs × 7 is equal to 7 billion.

7 billion = 70,000 lacs.

Therefore, as you can see, 70000 lacs is equal to 7 billion.

If we consider one Dollar is equal to 75 Indian Rupees, then 1 billion dollars in Indian National Rupee is equal to 75000000000.

Conversion From Billion to Crores

If you wish to convert the given billion value to crores in the Indian number system, then you should multiply the given billion value by 100 crores.

For example, you wish to convert 9 billion to crores in the Indian number system, then you should multiply 9 by 100 crores to get the desired result.

If we put it in another way, then you can also think that 9 × 100 crores is equal to 9 billion.

9 billion dollar = 900 crores.

Therefore, 9 billion is equal to nine hundred crores in words.

Likewise, you can convert any given billion value to values in the Indian number system such as crores, lacs, and many more.

How many Zeros in a Billion?

There are a total of 9 zeroes present in 1 billion value.

1 billion is equal to 1000000000.

How many Millions is a Billion?

For all of you who don’t know, 1 million is equal to 1000000.

That is, we can also say that 1000 thousand is equal to 1 million.

1000000000 is equal to 1000 million is equal to 1 billion.

So, the value of 1 billion is equal to 1000 million.

1 billion means

1 billion value can be represented by the letters bn and b. 1 billion is equal to 10000 lacs in the Indian number system.

Therefore, in terms of crores, 1 billion is equal to 100 crores that is 1 billion is equal to 1000000000.

Now, first of all, let’s consider that the value of $1 is 75 Indian rupees. Also, you know that the value of 1 billion is 1000000000 Indian Rupees. Therefore the value of 1 billion dollars in Indian rupees will be 75 × 10000000000 = 75000000000 Indian rupees. 1billion in lakhs On the basis of the position value chart, the international number system uses billions. Now we are going to find the equivalent of 1 billion in the Indian number system – 1 billion in Indian Rupees is equal to 100000000 Indian rupees. It can also be represented as – 1 billion is equal to 10000 lacs as all of us know that one lakh is equal to 100000. Therefore, 10000 lakh Indian Rupees is equal to 1 billion in lacs. We can also say that 1 billion lacs is equal to 10 million lacs. If you wish to convert 1 billion into crores, then we should bring this to your notice that 1 billion is equal to 100 crores. This is because one crore is equal to 10000000. 10 billion dollars in rupees As we have discussed 1 billion, now we will convert the given billion-dollar values in Indian national rupees. For instance, we have taken the value to be 10 billion dollars. So, let’s start with the basics first here in this segment. All of us know that the value of 1 billion till now. It is equal to 1000000000 Indian national rupees, which is also a natural number. The dollar conversion rate at the moment is around 74.42 Indian national rupee. But for ease of understanding and calculation, we have taken the value to be 75 Indian National rupees. So, for this segment and for all over this article, the value of 1 dollar is equal to 75 Indian national rupees as a matter of approximation. Now, before proceeding to the value of 10 billion dollars in rupees, let’s first calculate the value of 10 billion in rupees. Have a look at the simple formula written beneath – 10 billion is equal to 10 × 1 billion. i.e. 10 billion = 10 × 1000000000 = 10000000000 Indian National Rupees. Since we have got the value of 10 billion, now let’s move on to our next step and calculate the value of 10 billion dollars. 10 billion dollars can be easily calculated by multiplying 10 billion by the value of 1 dollar conversion and exchange rate. 10 billion dollars = 10 billion × 1 Dollar 10 billion dollars = 10000000000 × 75 10 billion dollars = 750000000000 Indian national rupees. The above-mentioned number is the representation of 10 billion dollars in Indian national rupees in numbers. It is also equal to 75 lac crores Indian rupees. If we talk about the representation of 10 billion dollars in words, then 10 billion dollars can be written as seventy-five lac crores Indian National rupees. 1 billion is equal to how many crores? A very frequent and common question related to 1 billion is that how much worth is one billion in crores? So, in this segment, we are going to answer this very interesting and commonly asked question. 1 billion = 1000000000 Indian national rupees. Now, if we calculate the total number of crores in the above-mentioned figure then the answer comes as 100 crores as 1 crore is equal to 10000000 Indian National Rupees. In words, one billion can be written or represented as hundred crores. Further, if one wants to convert one billion or hundred crores to lacs, the required answer will be ten thousand lacs. 1 billion = 10,000 lacs = 100 crores. One billion is equivalent to how many million? As established in the previous segment, 10,000 lacs = 100 crores = 1 billion Now, to convert one billion into millions or to answer the above question, one first needs to understand the concept of one million. One million is a term used in the international number system. It is equivalent to ten lakhs in the Indian number system. Therefore, 1 million = 10 Lakhs Indian National Rupees From the previous segment, 1 billion = Ten thousand lacs or 10000 lakhs. Dividing the second billion equation by the first million equation, we get 1 billion = 1000 lacs Indian rupees. In words, it can be written or represented as thousand lacs Indian National Rupees. 1.1 billion in crores So, amid converting all the integer value billions to lacs, crores and other place value in the Indian number system, now we will be trying and converting a decimal billion value to crores in the Indian number system. For this example, we will be taking our value as 1.1 billion. So, the only thing that you need to understand before proceeding on and solving this question is that you should know the value of 1 billion in number and its equivalent value in the Indian number system. As we have done numerous examples and questions on this topic till now, we hope that you are aware of the answers to both the above questions. The answer to the 1st question here is that the value of 1 billion is 1,000,000,000 Indian national rupees in numbers. If we translate that to crores or lakhs, we get our second answer. It is equivalent to 100 crores (or a hundred crores) Indian rupees in the Indian number system. So, keeping the above 2 points as notes, let’s start deducing the value of 1.1 billion in Indian National Rupees. The value of 1.1 billion can be deduced by multiplying 1.1 by 1 billion. Therefore, 1. × 1000000000 (One Billion) = 1.1 Billion 1100000000 = 1.1 Billion Therefore, 1100000000 Indian rupees is the value of 1.1 billion. This translates to 110 crores (one hundred and ten crores in words) or 11000 lacs (eleven thousand lakhs Indian rupees). 3 billion in rupees So, now let’s discuss about 3 billion and convert it into Indian national rupees. 1 Dollar is equal to 75 rupees (Assumption taken for this article). 1 billion is equal to 1000000000 Indian rupees in numbers. So, calculating 3 billion rupees becomes easy now as you just have to multiply 1 billion by 3. Therefore, 3 billion = 3 × 1000000000 Indian rupees = 3000000000 Indian rupees. If we talk about this number, then it is followed by 3000000001 and preceded by 2999999999. All of these are pure, natural numbers. It can be also written or represented as 300 crores or 30000 lacs. In words, it can be written as three hundred crores Indian rupees or thirty thousand lacs Indian rupees. 2 billion means All of us know that 1 billion is equal to 10000000000 which is a natural number. If we wish to calculate 2 billion by the same order and formula, then 2 billion will be equal to 2 X 1000000000 is equal to2000000000 Indian National Rupees. Therefore, 2 Billion means 2000000000 Indian rupees which is a natural number. The natural number 1999999999 comes before 2 billion and the natural number 2000000001 comes after 2 billion. In numbers, it is written or can be represented as 2 hundred crores or 20000 lacs. In words, 2 billion is equal to two hundred crores or twenty thousand lacs. 4 billion in rupees Assumption –$1 is equal to 75 Indian rupees.

1 billion = 1000000000 Indian rupees.

4 billion = 4 × 1 billion (1000000000 Indian rupees) = 4000000000 Indian rupees.

4 billion can also be written or represented as 400 crores or 40000 lacs.

In words, four billion is equal to four hundred crores Indian rupees or forty thousand lacs Indian rupees.

Now, as you know till now that we have considered the value of $1 as 75 Indian rupees. Also, you know that the value of 1 billion is 1000000000 Indian Rupees. So, the value of 5 billion is 5000000000 Indian rupees. Therefore, the value of 5 billion in Indian rupees is 500 crores (in crores) or 50,000 lacs. In words, the value can be written or represented as five hundred crores Indian rupees or fifty thousand lacs Indian rupees. 5 billion dollars in rupees in words All of us are now aware that 1 billion rupees are equal to 100000000 Indian rupees. Also, we hope that till now you are aware that we have considered the value of one dollar is equal to 75 Indian rupees. Therefore the value of 5 billion is equal to 5 x 100000000 and it will be equal to 500000000 Indian rupees. Therefore, the value of 5 billion dollars in Indian rupees is equal to 50000000 X 75 = 375000000000 Indian rupees. In words, it can be written as three lakh seventy-five thousand crores Indian rupees. 7 billion in rupees Coming to 7 billion in Indian rupees, we will go by the same logic that we have followed in the last few conversions of billions into the Indian national rupee.

Definition of circle

When a line AB rotate by 360 degree taking center A, thus obtained figure is called circle.

A is called center of circle. A to any point on the circle joining is called radius, a line passing through the center of the circle is called diameter of circle and its value is 2 * radius.

The ratio between circumference to diameter is always constant and denoted by its value is or 3.14 approximately.

Circumference of circle

so circumference of circle (p)=

Area of circle formula

Area of circle=
=

We divide a circle in to many small sectors, thus the length of an arc is reached near about the length of chord.

Then merge them as below we have obtained a ractangle.

Length of Chord

Length of chord=
where 2a=lengh of chord
h= height of arc

length of arc= arc/oce=Angle in degree/360
Radion: If are is equal in length to the radious, then the angle for form are called radion.

Segment of a circle

chord AB of a circle divides the circular region into two part, each part is called a segment of the circle.

Sector of the circle– the area surrounded by an arc and the two radius joining the end point of the arc with the center is called a sector of the circle.

Concentric circle– two or more circles with the given centre are called concentric circle.

Exponent

e.g

Square
The square of a number is the product of the number with the number itself
e.g. , ,
1,4,9,16,25……… are called perfect square.

To find the perfect square– factorize the given number, if their factors are in pair, then the number is perfect square,
e.g. is a perfect square.

Number perfect square.

No perfect square will end with 2,3,7,or 8 at the unit place.
A number having 0,1,4,5,6,9, in the unit place may or may not be a perfect number

(1) If the number has 1 or 9 at the unit place than its square and with 1
(2) The square of a number which has 4 or 6 at the units place will and in 6
(3) A number ending in an odd number of zero is never a perfect square.
E.g. 640, 5000, 44000
Between the square of the numbers n and n+1 there are 2n non perfect square numbers
, ,
, ,
, ,

The square of an even number is always an even number & the square of an odd number is always an odd number.
,
The secure of a natural number (expert ) is either or multiple of 3 or exceeds a multiple of 3 & 41

Similarly- with 4

The square of natural number ending with five follows a delimit pattern
52 = (0×1) hundred + 25 = 25
152 = (1×2) hundred + 25 = 225
252 = (2×3) hundreds + 25 = 625
352 = (3×4) hundred + 25 = 1225
452 = (4×5) hundred + 25 = 2025

The sum of first nodal natural numbers in n2
Sum of first odd number = 1 =12
Sum of first two odd number = 1+3 = 4 = 22
Sum of first three odd number = 1+3+5 = 9 = 32
The sum of rfirst four oddd number = 1+3+5+> = 16 =42

Look at this pattern whose number include only one.

12 = 1 ___________(= 12)
112 = 121 (1+2+1 = 4 = 22)
1112 = 12321 (1+2+3+2+1 = 9 = 32)
11112 = 1234321 (1+2+3+4+3+2+1 = 16 = 42)
111112 = 121 (1+2+3+4+5+4+3+2+1 = 25 = 52)

Square of these numbers is serially overdraft 1,2,3 …………..equal to the number of its digit & decreases vice verse ………3,2,1
The sum of the digit of their product is also a perfect square.

72 = 49 pattern- when number of digit = 1 than number of 4 = n, & number of 8 = n time +1
672 = 4489
6672 = 444889
666722 = 44448889

Pythagorean triplet
In right angled triangle:-
For any numbewr m>1, (2m, m2-1, m2 +1) is a Pythagorean triplet
If 3, 4, 5
M=2 22-1, 2×2, 22+1

Square root
The square root of the number , is that number, which when multiplied by itself , gives the number as the product.
√x×√x=x we denote the square root of x, by √x , square root is a inverse process, of square.
2×2 = 4 & √(4 )= √(2×2) = 2
Note:- if a number has a natural numbewr as square root then its units digit must be 0,1,4,5,6 or 9. Negative numbers have no square root in the system of natual numbers
e.g √25= ≠5
to find the square root by factorisation method
√16= √(4×4)=4
The number being the perfect square, will have one or more pairs of ther prime factor, write one factor from each pair & multiplied these factors , the product will be the square root of the number e.g√81= √(3×3×3×3)=3×3=9
To find square root by successive substraction method
The sum of the first n odd natural numbers is n2
This method is useful to find the square root of smaller natural numbers.
81-1 = 80
80-3 = 77
77-5 = 72
72-7 = 65
65-9 = 56
56-11 = 45
45-13 = 32
32-15 = 17
17-17 = 0
Square root by division method
e.g.
to find the number of digit in the square root
√((81) ̅ ) = 1 digit = 9
√(2 ̅(25) ̅ )=2 digit=25
√((20) ̅(25) ̅ )=2 digit=48
√(2 ̅8 ̅(224) ̅ )=3 digit=168
Square root of rational numbers(fraction)
√(a/b)= √a/√b
Square root of decimal
We see that 0.2 ×0.2 = 0.04 ∴ √(0.(04) ̅ ) = 0.2 number of digit 1 & root of 4 = 2
Approximate value of square root
We get the square of that number is multiplied by itself x×x = x2
Similarly if a number is multiplied by itself 3 times we get cube of that number x×x×x = x3
Perfect cube:- a natural number is said to be a perfect cube if it is the cube or a natural number.
e.g 13 = 1, 23 = 8, 33 = 27 thus 1,8,27 are perfect cube.
Properties:-
The cube of even numbers are even & odd number are odd.
In a perfect cube each prime numbers appears three times in its prime factorization √27= √(3×3×3)=
Cube of negative numbers is negative
Cube of number ending with 0,1,4,5,6 & 9 also end with the same digit ending with 8 will end with similarly cubes of number ending 3 &7 will end with 7 & 3 respectively.
Smallest number:- some numbers are expressed as the same of two square & sum of two cubes also.
c.g. :-
1729 = 1728 + 1 = 123 +1
1729 = 1000 + 729 = 103 + 93
4104 = 8 + 4096 = 23 + 163, 4104 = 729 + 3375 = 92 + 153
13832 = 5832 + 8000 = 183 + 203, 13832 = 8+13824 = 23 + 243
Cube root of decimal numbers
To find the cube root of aq decimal numbers, write the number in the form of p/q and then find their cube root
