Question

Medal and a fan for help with a couple of questions? (:

Answer 1

What is the value of \[2x ^{-2}y ^{-2}\] for x=3 and y=-2?

Answer 2

basically like any number raised to a negative number is 1/ positive of it. SO for example: 2^-2 is like saying 1 / 2^2 = 1/4. with that in mind you can do that problem i guess

Answer 3

by like substituting the values that are given (x and y) :)
