(d^2)/(dx^2)(sqrt(x^2+81))

Lösung

\frac{d ^{2}}{d x ^{2}} (x^{2} + 81)

Lösung

\frac{81}{( x ^{2} + 81 ) x ^{2} + 81}

Schritte zur Lösung

\frac{d ^{2}}{d x ^{2}} (x^{2} + 81)

\frac{d}{d x} (x^{2} + 81) = \frac{x}{x ^{2} + 81}

= \frac{d}{d x} (\frac{x}{x ^{2} + 81})

\frac{d}{d x} (\frac{x}{x ^{2} + 81}) = \frac{81}{( x ^{2} + 81 ) x ^{2} + 81}

= \frac{81}{( x ^{2} + 81 ) x ^{2} + 81}
