Chapter 8.2, Problem 8CE

To determine

To Simplify: Simplify the given expression

Answer to Problem 8CE

The simplified form is ${\left(2n\right)}^2=4n^2$

Explanation of Solution

Given information: The given expression is ${\left(2n\right)}^2$

We have the given expression is ${\left(2n\right)}^2$

It can be further written as

  $\begin{array}{c}{\left(2n\right)}^2=\left(2n\right)\left(2n\right)\\ =4n^2\end{array}$

Since square root is positive quantity so we neglect negative sign.

Therefore, the simplified form is ${\left(2n\right)}^2=4n^2$
