Wait its kinda hard to read....is -2/3 the exponent???

2. abb0t Group Title

$27^{-\frac{ 2 }{ 3 }} = \frac{ 1 }{ \sqrt[3]{27^2} }$

3. abb0t Group Title

magic? $\sqrt{a}=a^\frac{ 1 }{ 2 }$ similarly: $\sqrt[100]{a}= a^{100}$ and: $a^{-1} = \frac{ 1 }{ a^1 }= \frac{ 1 }{ a }$

4. abb0t Group Title

sorry, the second one should be: $\sqrt[100]{a} = a^\frac{ 1 }{ 100 }$

5. abb0t Group Title

to be fully clear: $\sqrt[x]{a^y} = a^\frac{ y }{ x }$

6. Mertsj Group Title

Just remember: the bottom number is the root, the top number is the power. So what is the third root of 27?

7. Mertsj Group Title

Yes. The top number is the power which is 2 so what is 3 to the second power?

9. Mertsj Group Title

I can't see very well. Is there a negative sign in front of the 2/3?

10. Mertsj Group Title

If there it, it is 1/9

11. AriPotta Group Title

mmk. thanks :)

12. Mertsj Group Title

0k. Then it is 1/9. yw

13. abb0t Group Title

stepped out for a minute, sorry. but i see you got the answer. Good job.
