Simplify and Use Square Roots: example 9.10

Simplify: $\sqrt{64 p^{64}}$ .

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution
$\begin{matrix} \sqrt{64 p^{64}} \\ Since {(8 p^{32})}^{2} = 64 p^{64} . & 8 p^{32} \end{matrix}$

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Simplify: $\sqrt{49 x^{30}}$ .
