# How to find Square root and Cube root

## Square root

If you have to find square of a number then we write it means we multiplied x two times and got y.

For example find the square of 2 that you have to multiple 2 two times We find square of a number by multiplying that number twice.

So what is a square root

Finding a square root is reverse process of square.

In square root we find the number which is multiplied itself to get the square of number.

a square root is represented by symbol This symbol is known as square root.

here x represents the number whose square root we want to find

In general

if then ,  in above example

Square root of y is x
square root of 4 is 2
square root of 9 is 3

Example find the value of We all know 36 is square of 6

so we can write so = Find the  \sqrt{9*9}=9

Finde the square root of 625

by factoring 625

we get 625=5*5*5*5

so = =5*5

=25

To find the square root of 2 is as below

## Cube root

We can find cube of a number by multiplying it three times

for example to find cube root of x we multiply it tree times Here y is cube of x

Finding the cube of 2

that is here 8 is cube of 2

similar  Now what is cube root

Cube root is a reverse process of a cube.

In cube root we find the number which is multiplied itself thrice to get the cube of number. here is known as cube root of Cube root is represented by   here x is number whose cube root we want to fine

Finding Square & cube root by factorization
