Question

How the heck do you do this

Answer 1

The top one is 20 times as much but I really don't understand how to explain it.

Answer 2

If u know how exponents work, then you need to make the 10 into a 1000 and multiply it by 4.2. Then do the same process to the other # and divide the larger number by the smaller one. That it how you get the answer. Problem (1 or 2) is x times as much as the other problem.
