\frac{\partial}{\partial x} (2 y^{\frac{1}{2}} x^{\frac{1}{2}})

(\frac{y}{x})^{\frac{1}{2}}

Schritte zur Lösung

\frac{\partial}{\partial x} (2 y^{\frac{1}{2}} x^{\frac{1}{2}})

Behandle

y

als Konstante

Entferne die Konstante:

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

= 2 y^{\frac{1}{2}} \frac{\partial}{\partial x} (x^{\frac{1}{2}})

Wende die Potenzregel an:

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

= 2 y^{\frac{1}{2}} \frac{1}{2} x^{\frac{1}{2} - 1}

Vereinfache

2 y^{\frac{1}{2}} \frac{1}{2} x^{\frac{1}{2} - 1} : (\frac{y}{x})^{\frac{1}{2}}

= (\frac{y}{x})^{\frac{1}{2}}

f (x) = \frac{10}{x}

x \to 2 lim (\frac{x ^{2}}{x ^{2} - 4})
