Question

How many times larger is 8×10^9 than 2×10^7​

Answer 1

It is larger by
`4*10^2` times

Explanation:

You use exponential division for this problem

first, divide 8 by 2

8/2 = 4

Then, look at 10^9 and 10^7

The bases of those numbers are the same, so you can just subtract the exponents since you're dividing.

`10^9 / 10^7 = 10^(9-7) = 10^2`

Combine those two together to get:

4 * 10^2
