\frac{x ^{2} + 72 x ^{\frac{7}{8}}}{8 x ^{\frac{23}{8}}}

Solution steps

Apply the Sum/Difference Rule:

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

\frac{d}{d x} (\frac{9}{x}) = - \frac{9}{x ^{2}}

= \frac{1}{8 x ^{\frac{7}{8}}} - (- \frac{9}{x ^{2}})

Simplify

\frac{1}{8 x ^{\frac{7}{8}}} - (- \frac{9}{x ^{2}}) : \frac{x ^{2} + 72 x ^{\frac{7}{8}}}{8 x ^{\frac{23}{8}}}

= \frac{x ^{2} + 72 x ^{\frac{7}{8}}}{8 x ^{\frac{23}{8}}}

x \to 3 lim (x^{2} + x)

y = ln (x^{2} + 5)

n = 1 \sum \infty \frac{1}{4 n - 2}

\frac{\partial}{\partial x} (x^{2} + 2 y^{2} + 3 z^{2} - 1)

\int 7 ln (x^{2} - 1) d x
