Question

TIMED, does anyone know the answer?

Answer 1

Answer:

D

Step-by-step explanation:

128/2 = 64

The squareroot of 64 = 8

That means that only C or D could be true; 8 is in the numerator not the denominator.

Look at the ys next. There are 5 in the denominator and 6 in the numerator. Five of them will cancel out leaving 1 in the numerator. That makes D the answer. However we should check out the xs.

There are 5 in the numerator and 7 in the denominator. That means that there are 2 left in the denominator. Since the xs are squared in the denominator, to remove the square root sign, you need to take out 1 x from under the root sign and throw the other one away.

Answer 8sqrt(y)/x
