(3 + x^{2})^{2} x : 9 x + 6 x^{3} + x^{5}

= \int_{0}^{1} 9 x + 6 x^{3} + x^{5} 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_{0}^{1} 9 x d x + \int_{0}^{1} 6 x^{3} d x + \int_{0}^{1} x^{5} d x

\int_{0}^{1} 9 x d x = \frac{9}{2}

\int_{0}^{1} 6 x^{3} d x = \frac{3}{2}

\int_{0}^{1} x^{5} d x = \frac{1}{6}

= \frac{9}{2} + \frac{3}{2} + \frac{1}{6}

Vereinfache

\frac{9}{2} + \frac{3}{2} + \frac{1}{6} : \frac{37}{6}

= \frac{37}{6}
