Chapter 8: Q. 76 (page 771)

In the following exercises, simplify using absolute value signs as needed. $\sqrt{96 r^{3} s^{3}}, \sqrt[3]{80 x^{7} y^{6}}, \sqrt[4]{80 x^{8} y^{9}}$

Short Answer

Expert verified

The expression on simplification is $4 | r s | \sqrt{6 r s}, 2 x^{2} y^{2} \sqrt[3]{10 x}, 2 x^{2} y^{2} \sqrt[4]{5 y}$ respectively

Step by step solution

Given information

Given the expression $\sqrt{96 r^{3} s^{3}}, \sqrt[3]{80 x^{7} y^{6}}, \sqrt[4]{80 x^{8} y^{9}}$

Using the product property

Using the product property, we get

$\sqrt{96 r^{3} s^{3}} = \sqrt{16 r^{2} s^{2} 路 6 r s} \sqrt{96 r^{3} s^{3}} = \sqrt{(4 r s)^{2} 路 6 r s} \sqrt{96 r^{3} s^{3}} = \sqrt{(4 r s)^{2}} 路 \sqrt{6 r s} \sqrt{96 r^{3} s^{3}} = 4 | r s | \sqrt{6 r s}$

Using the product property

Using the property, we get

$\sqrt[3]{80 x^{7} y^{6}} = \sqrt[3]{8 x^{6} y^{6} 路 10 x} \sqrt[3]{80 x^{7} y^{6}} = \sqrt[3]{{(2 x^{2} y^{2})}^{3} 路 10 x} \sqrt[3]{80 x^{7} y^{6}} = \sqrt[3]{{(2 x^{2} y^{2})}^{3}} 路 \sqrt[3]{10 x} \sqrt[3]{80 x^{7} y^{6}} = 2 x^{2} y^{2} \sqrt[3]{10 x}$

Using the product property

Using the property, we get

$\sqrt[4]{80 x^{8} y^{9}} = \sqrt[4]{16 x^{8} y^{8} 路 5 y} \sqrt[4]{80 x^{8} y^{9}} = \sqrt[4]{{(2 x^{2} y^{2})}^{4} 路 5 y} \sqrt[4]{80 x^{8} y^{9}} = \sqrt[4]{{(2 x^{2} y^{2})}^{4}} 路 \sqrt[4]{5 y} \sqrt[4]{80 x^{8} y^{9}} = 2 |x^{2} y^{2}| \sqrt[4]{5 y} \sqrt[4]{80 x^{8} y^{9}} = 2 x^{2} y^{2} \sqrt[4]{5 y}$
