Rewrite the rational exponent as a radical by extending the properties of integer exponents. (more below)

anonymous · Answer

$$\frac{ 2^{\frac{7}{8}}}{ 2^{\frac{1}{4}} }$$
I got $$\sqrt[8]{2^5}$$

directrix · Answer

I got that, too.

anonymous · Answer

because when it is set up like that you subtract the exponents to get 5/8, and the 5 goes under the radical while the 8 goes on the outside

anonymous · Answer

ok thanks its my first time doing radicals wanna make sure i start off good. i didn't start off great in functions

directrix · Answer

That "outside" is called the index. The index of your radical answer is 8.

directrix · Answer

You are off to a good start.

anonymous · Answer
