How do I simplify this?
I believe this would be the solution.
First of all, turn the entire problem (except for the exponent) upside down. This will change the sign of your exponent (-2) to positive (2).(x)^2=x^2(y^4)^2 = y^8The new numerator is thus (x^2)(y*8). What's the denominator going to look like?
