Hello,

I have an equation I need to differentiate but I'm not sure where I'm going wrong.

I've uploaded a copy of the question with my working as it's a bit easier as opposed to typing it all out.

The question itself (it's cut off slightly on the pic) is...

$\displaystyle {3x^3 + 6} / {xE(2/3)}$

If someone could give me a tip where I'm going wrong, that would be appreciated..
