To determine

To Simplify: Simplify the given expression

Answer to Problem 7CE

The simplified form is $\sqrt{225}=15$

Explanation of Solution

Given information: The given expression is $\sqrt{225}$

We have the given expression is $\sqrt{225}$

It can be further written as

  $\begin{array}{c}\sqrt{225}=\sqrt{{\left(15\right)}^2}\\ =15\end{array}$

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

Therefore, the simplified form is $\sqrt{225}=15$
