Short Answer

Expert verified

On simplifying the we get the result as

ⓐ 6

ⓑ 13

Step by step solution

Step 1. Given information

The given numbers are

$\begin{array}{l} a) \sqrt{36} \\ b) \sqrt{169} \\ c) - \sqrt{225} \end{array}$

We have to simplify the terms.

Step 2. calculate the square root for part (a)

$\begin{array}{l} Wehave \sqrt{36} \\ {Since6}^{2} = 36 \\ Thus, \\ \Rightarrow \sqrt{36} = 6 \end{array}$

Step 3. calculate the square root for part (b)

$\begin{array}{l} Wehave \sqrt{169} \\ {Since13}^{2} = 169 \\ Thus, \\ \Rightarrow \sqrt{169} = 13 \end{array}$

Step 3. calculate the square root for part (b)

$\begin{array}{l} Wehave - \sqrt{225} \\ {Since15}^{2} = 225 \\ Thenegativeisinfrontoftheradicalsign. \\ Thus, \\ \Rightarrow - \sqrt{225} = - 15 \end{array}$
