(d^2)/(dx^2)(sqrt(x+7))

Lösung

\frac{d ^{2}}{d x ^{2}} (x + 7)

Lösung

- \frac{1}{4 ( x + 7 ) ^{\frac{3}{2}}}

Schritte zur Lösung

\frac{d ^{2}}{d x ^{2}} (x + 7)

\frac{d}{d x} (x + 7) = \frac{1}{2 x + 7}

= \frac{d}{d x} (\frac{1}{2 x + 7})

\frac{d}{d x} (\frac{1}{2 x + 7}) = - \frac{1}{4 ( x + 7 ) ^{\frac{3}{2}}}

= - \frac{1}{4 ( x + 7 ) ^{\frac{3}{2}}}
