Question 547232: %28-33x%5E4y%5E-2%29%2F3x%5E7y%5E4
I know that you have to subtract exponents, but what do I do when the answer would be negative?
Also, the instructions tell me to simplify the expression with positive exponents.

%28-33x%5E4y%5E-2%29%2F3x%5E7y%5E4
%28-33%2F3%2Ax%5E%284-7%29%2Ay%5E%28-2-4%29%29
%28-11%2Ax%5E%28-3%29%2Ay%5E%28-6%29%29
%28-11%2Ax%5E%28-3%29%2Ay%5E%28-6%29%29
Though this expression is right, if we want positive exponents we can bring everything with a negative exponent to the denominator and make the exponents positive by one of our exponent laws.
%28-11%29%2F%28x%5E%283%29%2Ay%5E%286%29%29
