Using the general power rule to find the derivative of the function

$\displaystyle f(x)= {({x}^{2 }-9 })^{\frac{2}{3 } } $

in this case do they mean the chain rule...if not then i'm not sure how to expand the function

in order to use the chain rule, you will have to invoke the power rule as well. you have: (something)^(a power).
