\frac{d}{d x} (x + \frac{7}{x})

\frac{1}{2 x} - \frac{7}{2 x ^{\frac{3}{2}}}

Solution steps

\frac{d}{d x} (x + \frac{7}{x})

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (x) + \frac{d}{d x} (\frac{7}{x})

\frac{d}{d x} (x) = \frac{1}{2 x}

\frac{d}{d x} (\frac{7}{x}) = - \frac{7}{2 x ^{\frac{3}{2}}}

= \frac{1}{2 x} - \frac{7}{2 x ^{\frac{3}{2}}}
