\frac{x ^{2} + 56 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{7}{x}) = - \frac{7}{x ^{2}}

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

Simplify

\frac{1}{8 x ^{\frac{7}{8}}} - (- \frac{7}{x ^{2}}) : \frac{x ^{2} + 56 x ^{\frac{7}{8}}}{8 x ^{\frac{23}{8}}}

= \frac{x ^{2} + 56 x ^{\frac{7}{8}}}{8 x ^{\frac{23}{8}}}

- x^{- 2} e^{\frac{1}{x}}

5 + 4 x^{2} - 2 x^{3}

\frac{x}{8} - \frac{8}{x}

y^{^{''}} - 7 y^{^{'}} + 6 y = 0

\int \frac{y ^{3}}{y ^{2} + 1} d y
