Hi guys(adsbygoogle = window.adsbygoogle || []).push({});

I was wondering after reading some other stuff on the web..

How much is [itex](-1)^{2/6}[/itex]

It is [itex](-1)^{\frac{2}{6}}=(-1)^{\frac{1}{3}}=\sqrt[3]{-1}=-1[/itex]

OR

[itex](-1)^{\frac{2}{6}}=\sqrt[6]{(-1)^2}=\sqrt[6]{1}=1[/itex]

I'm really confused with this...

Any suggestions?

Thanks

João
