Lösung

ableitung von

f (x) = x^{\frac{9}{2}} e^{x}

Lösung

\frac{9 e ^{x} x ^{\frac{7}{2}}}{2} + e^{x} x^{\frac{9}{2}}

Schritte zur Lösung

\frac{d}{d x} (x^{\frac{9}{2}} e^{x})

Wende die Produktregel an:

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

f = x^{\frac{9}{2}}, g = e^{x}

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

\frac{d}{d x} (x^{\frac{9}{2}}) = \frac{9 x ^{\frac{7}{2}}}{2}

\frac{d}{d x} (e^{x}) = e^{x}

= \frac{9 x ^{\frac{7}{2}}}{2} e^{x} + e^{x} x^{\frac{9}{2}}
