Question

use rational exponents to write single radical expression:
^4√8 * ^2√7

Answer 1

First, use the fact that

\[\sqrt[n]{x^m}=x^{\frac{m}{n}}\]


to rewrite \[\sqrt[4]{8}\] into \[8^{\frac{1}{4}}\]

and to rewrite \[\sqrt[2]{7}\] into \[7^{\frac{1}{2}}\]


So after all that, you now have the expression \[8^{\frac{1}{4}}7^{\frac{1}{2}}\] see what you can do with that.

i'm not understanding

Answer 3

I'm converting radical expressions (expressions with roots) into expressions that involve exponents only.
