Hi,

I was reading a textbook when I came upon their discussion on De Moivre's Theorem. The book talked about the difference between $\displaystyle (-8)^{\frac{1}{3}}$ and $\displaystyle (-8)^{\frac{2}{6}}$, and they said something about how De Moivre's Theorem let us conclude that there are 3 cube roots of a number and 6 sixth roots. Can anyone decipher what this means?

Thanks!
