Question

Simplify the given value.

ⓐ $\sqrt{196}$ⓑ$-\sqrt{1}$

Short answer

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

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

Part (b)  Step 3. Given informaiton

ⓑ$-\sqrt{1}$

Simplify the given information

Step 4. Explanation

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