Question

subtract: (5b^8 + 4v) - (-7b^8). your answer should be in simplest terms. enter the correct answer.

Explanation:

Step1: Remove parentheses

When we have \((5b^{8}+4v)-(- 7b^{8})\), removing the parentheses gives \(5b^{8}+4v + 7b^{8}\) since \(-(-7b^{8})=7b^{8}\).

Step2: Combine like - terms

The like - terms are \(5b^{8}\) and \(7b^{8}\). Combining them, we get \((5 + 7)b^{8}+4v=12b^{8}+4v\).

Answer:

\(12b^{8}+4v\)
