Chapter 8.1, Problem 2WE

To determine

The given expression.

Answer to Problem 2WE

The simplified form is $\sqrt{72}=6\sqrt{2}$ .

Explanation of Solution

Given information:

The given expression is $\sqrt{72}$ .

The given expression is $\sqrt{72}$

It can be further written as

  $\begin{array}{c}\sqrt{72}=\sqrt{2^2\times 3^2\times 2}\\ =2\times 3\sqrt{2}\\ =6\sqrt{2}\end{array}$

Since square root is positive quantity so neglecting negative sign.

Therefore, the simplified form is $\sqrt{72}=6\sqrt{2}$
