The answer is D

Step-by-step explanation:

Whenever a exponent is take from the bottom of a fraction it will change inversely and become either a positive or negative. For example since the exponent is -4 for C you will change it to +4 when you bring it to the top of the fraction or the numerator. You can also plug in numbers and solve to verify your

C = 2

D = 2

So, when we plug in these numbers we get the same result so your answer is

D.

the answer is d

step-by-step explanation:
