Simplify; express answer with only positive exponents.
:
square both terms in the denominator
%28-x%5E-4%2Ay%5E3%29%2F%286y%5E-2%29%5E2 = %28-x%5E-4%2Ay%5E3%29%2F%286%5E2%2Ay%5E%28-2%2A2%29%29 = %28-x%5E-4%2Ay%5E3%29%2F%2836%2Ay%5E-4%29
Reciprocal will get rid of the negative exponent
%28y%5E3%2Ay%5E4%29%2F%2836%28-x%5E4%29%29 = %28y%5E7%29%2F%28-36x%5E4%29%29 = -%28y%5E7%29%2F%2836x%5E4%29%29
