As soon as you see variables and Quant Comp, make your set-up.
Plugging In is tricky here until you realize that one number must be negative. The 6 in Quantity B is also a clue. Try x = 3 andy = -2. y to the x power will be -8 and x to the y power will be 1/9, so these numbers work. xy = -6 so cross off choices (A) and (C). No matter what you plug in, y must be negative and x must be odd. Therefore xy will always be negative and 6 will always be greater. The answer is choice (B).

I'm a little confused, because 1/9 is not between -1 and 0. I understand the logic behind the rest of the question, but not that part. Do you mind explaining a bit more?
