## anonymous 3 years ago 9^-1/5. Write in Radical Form.

1. anonymous

Firstly, $\huge x^{-\frac{a}{b}} \implies \sqrt[b]{x^{-a}}$ and: $\huge x^{-a} = \frac{1}{x^a}$

2. anonymous

So I have to find the radical first then, place it in a form without the negative exponent?

3. anonymous

Yep...

4. anonymous

Or you can leave it in negative form in the radical also, there is no harm..

5. anonymous

6. anonymous

You tell me first, I will check it for you..

7. anonymous

Is it $\frac{ 1 }{ \sqrt[5]{9} }$

8. anonymous

Oh sorry, YES IT IS RIGHT..

9. anonymous

Oh. Lol Thank you so much then, just looing for confirmation, This homework doesnt have an answer sheet,
