Question

Simplify. Assume that the variable represents a positive real number sqrt[(7c)]^2

Answer 1

Answer:
`^{}(\sqrt[]{7c}^{})^2=7c`

Step-by-step explanation:

Given

`^{}(\sqrt[]{7c}^{})^2`

This can be written as:

`\begin{gathered} ((7c)^{(1)/(2)})^2 \\ \\ =(7c)^{(2)/(2)} \\ \\ =(7c)^1=7c \end{gathered}`
