Chapter 8: Q. 6 (page 755)

ⓐ $\sqrt{\frac{64}{121}}$ ⓑ $- \sqrt{0.04}$

Short Answer

Expert verified

Part (a) $\sqrt{\frac{64}{121}} = \frac{8}{11}$

Part (b) $- \sqrt{0.04} = 0.2$

Step by step solution

Part (a). Step 1 Given information

ⓐ $\sqrt{\frac{64}{121}}$

Simplify the given value.

Step 2. Explanation

Since $\begin{array}{l} \begin{array}{l} \begin{array}{l} \Rightarrow {(8)}^{2} = 64 \\ \Rightarrow {(11)}^{2} = 121 \end{array} \\ \Rightarrow \sqrt{\frac{64}{121}} = \sqrt{{(\frac{8}{11})}^{2}} \\ = \frac{8}{11} \end{array} \end{array}$

Part (b) Step 3. Given information.

ⓑ $- \sqrt{0.04}$

Simplify the given value.

Step 4.Explanation

Since $\Rightarrow - \sqrt{0.04} = - \sqrt{{(0.2)}^{2}} = - 0.2$
