log derivative and chain rule should get you there.

You need to brush up on your algebra. ##\sqrt[3]{x}## doesn't mean ##(\sqrt{x})^3##; it means ##x^{1/3}##. Try again.

If you must post your attempt at a solution in handwritten form, at least use a clean sheet of paper and present your work in some logical sequence so that others can follow it. o_O

@thegoosegirl42,
The image you posted was so bad that I deleted it. Please post the problem you want help on (not an image), together with your work.
