SOLUTION: Hi! How do I simplify the following: (x^-4+y^-2)/(x^-6+y^-4) ? The automatic simplifier only goes this far (1/x^4+1/y^2)/(1/x^6+1/y^4), and if I continue from there

Question 802368: Hi!
How do I simplify the following:
(x^-4+y^-2)/(x^-6+y^-4)
?
The automatic simplifier only goes this far
(1/x^4+1/y^2)/(1/x^6+1/y^4), and if I continue from there I managed to somehow get simplify it to x^2y^2 but as I have no answer key, any help would be appreciated! Thanks!

You can put this solution on YOUR website!
%28x%5E-4%2By%5E-2%29%2F%28x%5E-6%2By%5E-4%29
I am pretty sure that
%281%2Fx%5E4%2B1%2Fy%5E2%29%2F%281%2Fx%5E6%2B1%2Fy%5E4%29
is as far as you can go.
