(\partial)/(\partial x)(x^4+6sqrt(y)-10)

解

\frac{\partial}{\partial x} (x^{4} + 6 y - 10)

4 x^{3}

解答ステップ

\frac{\partial}{\partial x} (x^{4} + 6 y - 10)

y

を定数として扱う

和/差の法則を適用:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial x} (x^{4}) + \frac{\partial}{\partial x} (6 y) - \frac{\partial}{\partial x} (10)

\frac{\partial}{\partial x} (x^{4}) = 4 x^{3}

\frac{\partial}{\partial x} (6 y) = 0

\frac{\partial}{\partial x} (10) = 0

= 4 x^{3} + 0 - 0

簡素化

= 4 x^{3}
