Exercise 6 Page 419

Before multiplying the given radical expressions, we need to answer two questions.

1. Can the expressions be multiplied?
2. If so, do absolute value symbols need to be added to the answer?

The rule regarding multiplying radical expressions states that if $\sqrt[n]{a}$ and $\sqrt[n]{b}$ are real numbers, then $\sqrt[n]{a}\cdot \sqrt[n]{b}$ $=$ $\sqrt[n]{ab}.$
