Chapter 8: Q. 72 (page 771)

In the following exercises, simplify using absolute value signs as needed. $\sqrt{80 s^{15}}, \sqrt[5]{96 a^{7}}, \sqrt[6]{128 b^{7}}$

Short Answer

Expert verified

The expression in simplified form is $4 s^{6} \sqrt{5 s^{3}}, 2 a \sqrt[5]{3 a^{2}}, 2 | b | \sqrt[6]{2 b}$ respectively

Step by step solution

Given information

Given the expression $\sqrt{80 s^{15}}, \sqrt[5]{96 a^{7}}, \sqrt[6]{128 b^{7}}$

Using the product property

Using the property, we get

$\sqrt{80 s^{15}} = \sqrt{16 s^{12} 路 5 s^{3}} \sqrt{80 s^{15}} = \sqrt{{(4 s^{6})}^{2} . 5 s^{3}} \sqrt{80 s^{15}} = \sqrt{{(4 s^{6})}^{2}} 路 \sqrt{5 s^{3}} \sqrt{80 s^{15}} = = 4 |s^{6}| \sqrt{5 s^{3}} \sqrt{80 s^{15}} = 4 s^{6} \sqrt{5 s^{3}}$

Using the product property

Using the property, we get

$\sqrt[5]{96 a^{7}} = \sqrt[5]{32 a^{5} 路 3 a^{2}} \sqrt[5]{96 a^{7}} = \sqrt[5]{(2 a)^{5}} 路 \sqrt[5]{3 a^{2}} \sqrt[5]{96 a^{7}} = 2 a \sqrt[5]{3 a^{2}}$

Using the product property

Using the property, we get

$\sqrt[6]{128 b^{7}} = \sqrt[6]{64 b^{6} 路 2 b} \sqrt[6]{128 b^{7}} = \sqrt[6]{(2 b)^{6} 路 2 b} \sqrt[6]{128 b^{7}} = \sqrt[6]{(2 b)^{6}} 路 \sqrt[6]{2 b} \sqrt[6]{128 b^{7}} = 2 | b | \sqrt[6]{2 b}$
