Chapter 8: Q. 8.15 (page 751)

Simplify: $(a) \sqrt{y^{18}} (b) \sqrt{z^{12}}$

Short Answer

Expert verified

The solutions of (a) and (b) are $|y^{9}| a n d z^{6}$ respectively.

Step by step solution

Part (a) Step 1. Given information

The root: $\sqrt{y^{18}}$

Part (a) Step 2. Calculation

We have,

$\sqrt{y^{18}} = \sqrt{{(y^{9})}^{2}} \sin c e {(y^{9})}^{2} = y^{18} = |y^{9}| \sin c e t h e i n d e x n i s e v e n \sqrt{a^{n}} = |a|$

Therefore, the solution is $|y^{9}|$

Part (b) Step 2. Given information

The root: $\sqrt{z^{12}}$

Part (b) Step 2. Calculation

We have,

$\sqrt{z^{12}} = \sqrt{{(z^{6})}^{2}} \sin c e {(z^{6})}^{2} = z^{12} = z^{6}$

In this case, the absolute value sign is not needed as $z^{6}$ is positive.

Therefore, the solution is $z^{6}$
