x (x^{2} + 1)^{2} : x^{5} + 2 x^{3} + x

= \int_{0}^{3} x^{5} + 2 x^{3} + x 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}^{3} x^{5} d x + \int_{0}^{3} 2 x^{3} d x + \int_{0}^{3} x d x

\int_{0}^{3} x^{5} d x = \frac{243}{2}

\int_{0}^{3} 2 x^{3} d x = \frac{81}{2}

\int_{0}^{3} x d x = \frac{9}{2}

= \frac{243}{2} + \frac{81}{2} + \frac{9}{2}

Vereinfache

\frac{243}{2} + \frac{81}{2} + \frac{9}{2} : \frac{333}{2}

= \frac{333}{2}
