Answer 1

`2.48*10^(10)`

Step-by-step explanation:

Given the expression (3.96 x 10^2)/(1.6 x 10^-8), we are to express in scientific notation. Applying one of the laws of indices which says;

`(a^m)/(a^n) = a^(m-n)`

The expression becomes;

`= (3.96)/(1.6)*(10^2)/(10^(-8))\\ \\= (3.96)/(1.6)*10^(2-(-8))\\\\= (3.96)/(1.6)*10^(2+8)\\\\= (3.96)/(1.6)*10^(10)\\\\= 2.475*10^(10)\\\\= 2.48*10^(10) (to \ 2dp)`
