Multipliziere aus

(4 x^{2} + 9)^{2} : 16 x^{4} + 72 x^{2} + 81

= \int 16 x^{4} + 72 x^{2} + 81 d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 16 x^{4} d x + \int 72 x^{2} d x + \int 81 d x

\int 16 x^{4} d x = \frac{16 x ^{5}}{5}

\int 72 x^{2} d x = 24 x^{3}

\int 81 d x = 81 x

= \frac{16 x ^{5}}{5} + 24 x^{3} + 81 x

Füge eine Konstante zur Lösung hinzu
