Step-by-step explanation:
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
