Answer:

E) b^2

Step-by-step explanation:

Solving the first equation for a, we get ...

a - b = 0

a = b . . . . . . add b to both sides

Compare the values 4x107 is what times as much as 4x103

dezoksy [38]

Answer:

$10^{4}$

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
