You are way out in left field this time, Bub.

Use the property:



The -24 coefficient is correct, but a minus sign on a coefficent has NO effect on the sign of an exponent.



and remember, anything to the zero power is 1 (NOT 1x, just 1. If you are confused by this idea, write back and I'll give you a "makes good sense" explanation). Then

%28-3x%5E2y%5E2%29+%2A+%288x%5E-2y%5E3%29
Multiply --> add exponents
Add the exponents of x: 2 + (-2) = 0 for x
2 + 3 for y = 5
= -24x%5E0y%5E5
= -24y%5E5
