derivative of \sqrt[9]{x}-3/x

Solution

Solution

\frac{x ^{2} + 27 x ^{\frac{8}{9}}}{9 x ^{\frac{26}{9}}}

Solution steps

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

\frac{d}{d x} (\frac{3}{x}) = - \frac{3}{x ^{2}}

= \frac{1}{9 x ^{\frac{8}{9}}} - (- \frac{3}{x ^{2}})

Simplify

\frac{1}{9 x ^{\frac{8}{9}}} - (- \frac{3}{x ^{2}}) : \frac{x ^{2} + 27 x ^{\frac{8}{9}}}{9 x ^{\frac{26}{9}}}

= \frac{x ^{2} + 27 x ^{\frac{8}{9}}}{9 x ^{\frac{26}{9}}}
