f (x) = x^{\frac{5}{11}} (x - 5)^{2}

\frac{27 x ^{2} - 160 x + 125}{11 x ^{\frac{6}{11}}}

Schritte zur Lösung

\frac{d}{d x} (x^{\frac{5}{11}} (x - 5)^{2})

Wende die Produktregel an:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x^{\frac{5}{11}}, g = (x - 5)^{2}

= \frac{d}{d x} (x^{\frac{5}{11}}) (x - 5)^{2} + \frac{d}{d x} ((x - 5)^{2}) x^{\frac{5}{11}}

\frac{d}{d x} (x^{\frac{5}{11}}) = \frac{5}{11 x ^{\frac{6}{11}}}

\frac{d}{d x} ((x - 5)^{2}) = 2 (x - 5)

= \frac{5}{11 x ^{\frac{6}{11}}} (x - 5)^{2} + 2 (x - 5) x^{\frac{5}{11}}

Vereinfache

\frac{5}{11 x ^{\frac{6}{11}}} (x - 5)^{2} + 2 (x - 5) x^{\frac{5}{11}} : \frac{27 x ^{2} - 160 x + 125}{11 x ^{\frac{6}{11}}}

= \frac{27 x ^{2} - 160 x + 125}{11 x ^{\frac{6}{11}}}

\frac{\partial}{\partial x} (\frac{3 x + 2 y}{y ^{2} + 5 x ^{2}})

\int 3 + 4 x d x

\int \frac{1}{x ^{4} 4 - x ^{2}} d x
