The correct answer for this would be B
Answer:

Step-by-step explanation:
4 x 10^7 is 40000000
4 x 10^3 is 4000
We are told that 4x10^7 is something times as much as 4x10^3
So we will work backwards to find the answer,
If you divide 40000000 by 4000 you will get 10000
10000 is the same as 10^4
The second one is the only equivalent equation. Simply plug in each variable in each equation. And compare!
