\frac{d}{d x} (\frac{1}{2 x} + \frac{1}{9 x ^{\frac{8}{9}}})

- \frac{1}{4 x ^{\frac{3}{2}}} - \frac{8}{81 x ^{\frac{17}{9}}}

Solution steps

\frac{d}{d x} (\frac{1}{2 x} + \frac{1}{9 x ^{\frac{8}{9}}})

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (\frac{1}{2 x}) + \frac{d}{d x} (\frac{1}{9 x ^{\frac{8}{9}}})

\frac{d}{d x} (\frac{1}{2 x}) = - \frac{1}{4 x ^{\frac{3}{2}}}

\frac{d}{d x} (\frac{1}{9 x ^{\frac{8}{9}}}) = - \frac{8}{81 x ^{\frac{17}{9}}}

= - \frac{1}{4 x ^{\frac{3}{2}}} - \frac{8}{81 x ^{\frac{17}{9}}}

\int_{1}^{2} \frac{x - 1}{x} d x

\int e^{x} \cdot 2 x d x

\int \frac{t ^{2}}{1 + t ^{6}} d t

\frac{w}{w + \frac{c}{w}}

y = x^{2} - 6, at x = a
