-8x to the 5th power y to the 5th power +(-5x to the 5th power y to the 5th power)
-------------------------
-8x^5*y^5 + (-5x^5y^5)
The terms are like terms so combine them to get:
= -13x^5y^5

Simplify:
-8x%5E5y%5E5%2B%28-5x%5E5y%5E5%29 First, you could factor the common factor of x%5E5y%5E5 to get:
%28x%5E5y%5E5%29%28-8%2B%28-5%29%29 Now add the -8 and the -5 to get -13, so now you have:
highlight%28-13x%5E5y%5E5%29
