Thank you very much in advance. Now this one has me confused big time. It is suppose to be a "Short Answer!" Whatever that means....

If you mean:
%28%2845x%5E0y%5E2%29%5E-1%29%2F%28180x%5E-4y%5E-4%29
Do it one thing at a time.
x^0 = 1
%28%2845y%5E2%29%5E-1%29%2F%28180x%5E-4y%5E-4%29
= 1%2F%28%2845y%5E2%29%2A%28180x%5E-4y%5E-4%29%29
= 1%2F%2845%2A180y%5E-2%2Ay%5E-4%29
Multiply NUM and DEN by x^2y^4
= x%5E2y%5E4%2F8100
