Question

$log {10}^{2} + log {10}^{5}$
​

Answer 1

Answer: 7

Step-by-step explanation:

Before going to solve these type of questions u need to know some formulas,...

               $1)loga^{b}=bloga\\\\2)loga+logb=log(ab)$

..... and so on some other formulas.So

              $log10^{2}+log10^{5}\\\\=2log10+5log10\\\\=>log10(2+5)\\\\=>log10(7)\\\\=>7log10$

If the base of log is 10,

Then $log10^{2}+log10^{5}=7$

If it is natural logarithm then..

Then $log_{e}10^{2}+log_{e}10^{5}=2.302585*7=16.118$

Hope helps u ...
