Answer:
21b^7-30b^2 is the answer
Step-by-step explanation:
21b^7-30b^2 use the distributive
For this case we must simplify the following expression:
[tex]3b ^ 2 (7b ^ 5-10)[/tex]
We must apply distributive property. We take into account that to multiply powers of the same base we place the same base and add the exponents. So:
[tex]3b ^ 2 (7b ^ 5-10) =\\21b^2 + 5 -30b ^ 2 =\\21b ^ 7-30b ^ 2[/tex]
ANswer:
[tex]21b ^ 7-30b ^ 2[/tex]
