Let me try writing it again...
(X/2)^3*(X/2)^4

(X/2^3)^2
I keep getting X/2^6, but the book says X/2^5. How do you get X/2^5????

You keep the base and add the exponents
in the numerator
(x/2)^7
in the denominator it looks like you are raising a power to a power..
so you keep the base and multiply the two powers
denominator should be (x/2)^6
I don't know where the 5 is coming from in your answer... unless I am not understanding what the problem actually said or maybe you have a typo.
My answer would be x/2 because 7 6 = power of 1.

books have been know to be wrong, as do most teachers and students.
from the way you typed it, the simplified answer is
(x/2)^7 / (x/2)^6
= x/2
John1's explanation is correct
