You need to remember, a negative exponents turn integers into fractions". If they are already in fraction, it makes them a numerator.
%28%28%28-4%29%28x%5E4%29%28y%5E-2%29%29%2F%28%285%29%28x%5E-1%29%28y%5E4%29%29%29%5E-4
First distribute the -4;
16x%5E4y%5E-2%2F-20x%5E-1y%5E4
Now just switch the negative exponents;
16x%5E4x%5E1%2F-20y%5E2y%5E4
simplfy and add like terms;
-4x%5E5%2F5y%5E6
Hope you understand
=)
