Chapter 8.2, Problem 11CE

To determine

To Simplify: Simplify the given expression

Answer to Problem 11CE

The simplified form is ${\left(\frac{n}{\sqrt{3}}\right)}^2=\frac{n^2}{3}$

Explanation of Solution

Given information: The given expression is ${\left(\frac{n}{\sqrt{3}}\right)}^2$

We have the given expression is ${\left(\frac{n}{\sqrt{3}}\right)}^2$

It can be further written as

  $\begin{array}{c}{\left(\frac{n}{\sqrt{3}}\right)}^2=\left(\frac{n}{\sqrt{3}}\right)\left(\frac{n}{\sqrt{3}}\right)\\ =\left(\frac{n^2}{\sqrt{3}.\sqrt{3}}\right)\\ =\left(\frac{n^2}{\sqrt{3^2}}\right)\\ =\left(\frac{n^2}{3}\right)\end{array}$

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

Therefore, the simplified form is ${\left(\frac{n}{\sqrt{3}}\right)}^2=\frac{n^2}{3}$
