Behandle

y

als Konstante

Entferne die Konstante:

(a \cdot f)^{'} = a \cdot f^{'}

= y^{0.9} \frac{\partial}{\partial x} (x^{0.1})

Wende die Potenzregel an:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= y^{0.9} \cdot 0.1 x^{0.1 - 1}

Vereinfache

y^{0.9} \cdot 0.1 x^{0.1 - 1} : \frac{0.1 y ^{0.9}}{x ^{0.9}}

= \frac{0.1 y ^{0.9}}{x ^{0.9}}
