ⓐ $\sqrt{196}$ ⓑ $- \sqrt{1}$

Short Answer

Expert verified

Part (a) $\Rightarrow \sqrt{196} = 14$

Part (b) $\Rightarrow - \sqrt{1} = - 1$

Step by step solution

Part (a) Step 1. Given information

ⓐ $\sqrt{196}$

Simplify the given value

Step (2) Explanation

\begin{array}{l} \Rightarrow {(14)}^{2} = 196 \\ \Rightarrow \sqrt{196} = \sqrt{{(14)}^{2}} \\ = 14 \end{array}

Part (b) Step 3. Given informaiton

ⓑ $- \sqrt{1}$

Simplify the given information

Step 4. Explanation

Since $\begin{array}{l} \Rightarrow {(1)}^{2} = 1 \\ \Rightarrow - \sqrt{1} = - \sqrt{{(1)}^{2}} \\ = - 1 \end{array}$
