Multiply the coefficients (numbers in front).

for the letters with exponents. You keep the letter and you add the exponents.

Remember that y is y^1

Try it and I will check it for you.

-16x^2y^2x^3y^3??

(-8)(-2) that takes care of the coefficents = 16

(x^2)*(x^1) = x^3

(y^1)(y^3) = y^4

Now, put them all together and you will have the answer.
