Answer:

27x3+125y3+45xy

Step-by-step explanation:

Let's simplify step-by-step.

(3x+5y)3−45xy(3x+5y)+45xy

Distribute:

=27x3+135x2y+225xy2+125y3+−135x2y+−225xy2+45xy

Combine Like Terms:

=27x3+135x2y+225xy2+125y3+−135x2y+−225xy2+45xy

=(27x3)+(135x2y+−135x2y)+(225xy2+−225xy2)+(125y3)+(45xy)

=27x3+125y3+45xy
