You can put this solution on YOUR website!
%282%2F3%29x%5E-3y%5E5%2A%289%2F4%29x%5E3y%5E-3%29+

First, multiply the two fractions together. That would be
%282%2F3%29%2A%289%2F4%29=+18%2F12=3%2F2

As for the x and y factors, when you MULTIPLY, you ADD exponents, so you have
%283%2F2%29%2Ax%5E0%2Ay%5E2

Don't forget that x%5E0+=1.

Final Answer:
3y%5E2%2F2

R^2
