Solve for X
7^7/7^3 = 7^x

x = 4

Step-by-step explanation:

First, we must divide the two, its in a fraction, and as you should know, when we divide exponents, you subtract the exponent on the numerator by the exponent on the denominator. So in this case we are doing 7 - 3 which is equal to 5.

Then we still need to subtract from .

So our answer is

x = 4
