What is the easiest way to do this?when you change it to the reciprocal, do the positives become negatives?
Im assuming it looks like this:
(4x-4y7)2 / 24x-6y2
Here's my preferred method.
1) Distribute the square on the numerator
2) Subtract bottom exponents from top exponents, of similar base.
16/24 = 2/3
x-8/x-6 = x-8-(-6)=x-2
y14/y2 = y14-2 = y12
Now we have this.
Move negative powers down to the numerator.
