Differentiate the following with a positive index:(adsbygoogle = window.adsbygoogle || []).push({});

[itex]\frac{2}{\sqrt[3]{x}}[/itex]

What the book says:

[itex]\frac{-2}{3x^ \frac{2}{3}}[/itex]

But shouldn't it be:

[itex]\frac{-2}{3x^ \frac{4}{3}}[/itex]

I just wan't to know if I'm doing something wrong, thanks :).
