## Logarithms

[latexpage] It is a passive real number other than $a^m = n$ We write $m=log_a x$ $10^3 =1000$4 then we can write $log_{10} 1000 = 3$ $2^{-3} =\frac{1}{8}$ then we can write $log_2 \frac{1}{8} = -3$ Properties of logarithms $log_a (xy) = log_a x +log_a y$ $log_a (\frac{x}{y}) = log_a x – log_a y$ $log_x … Read more
