Given the expression:
[tex]-7v^3(-5v)[/tex]Let's simplify the expression.
First rearrange the expression using commutative property.
To simplify the expression, we have:
[tex]\begin{gathered} -7(-5)v^3(v) \\ \\ =35v^{3+1} \\ \\ =35v^4 \end{gathered}[/tex]Therefore, the simplified expression is:
[tex]35v^4[/tex]ANSWER:
[tex]35v^4[/tex]
