Question
Find the logarithm of : $100$ to the base $10$
✓
Answer
Let $log_{10}100 = x$
$\therefore 10^x = 100$
$\Rightarrow 10^x = 10 \times 10$
$\Rightarrow 10^x = 10^2$
$\Rightarrow x = 2 .....[\text { If } a^m = a^n \text { ; then } m = n ]$
$\therefore log_{10}100 = 2$
$\therefore 10^x = 100$
$\Rightarrow 10^x = 10 \times 10$
$\Rightarrow 10^x = 10^2$
$\Rightarrow x = 2 .....[\text { If } a^m = a^n \text { ; then } m = n ]$
$\therefore log_{10}100 = 2$
