Here is the question:
%289x%5E2y%2F%28-4x%5E3y%5E4%29%29+%2A+%2816x%5E4y%5E2%2F%2825xy%29%29
Simplify the left side of the product as
%289x%5E%28-1%29y%5E%28-3%29%2F%28-4%29%29+%2A+%2816x%5E4y%5E2%2F%2825xy%29%29
--
Simplify the right side of the product as
%289x%5E%28-1%29y%5E%28-3%29%2F%28-4%29%29+%2A+%2816x%5E3y%5E1%2F%2825%29%29
--
Multiply the numerators together as:
144x%5E%282%29y%5E%28-2%29%2F%28-4%29+%2A+1%2F%2825%29
--
multiply the denominators together as
144x%5E%282%29y%5E%28-2%29%2F%28-100%29
reduce the coefficients to get
-72x%5E%282%29y%5E%28-2%29
