Question

Which is equivalent to 8/10^−2 ? A) 800 B) 1 80 C) 80 D) 100 8

Answer 1

A) 800

Explanation:

Base 10 works like this, for example

`8 * 10^(2) = 80 * 10^(1) = 800`

`8 * 10^(-2) = 0.8 * 10^(-1) = 0.08`

So

`10^(-2) = 0.1 * 10^(-1) = 0.01`

So

`(8)/(10^(-2)) = (8)/(0.01) = 800`

So the correct answer is:

A) 800
