x^{4} (1 - x)^{3} : x^{4} - 3 x^{5} + 3 x^{6} - x^{7}

= \int_{0}^{1} x^{4} - 3 x^{5} + 3 x^{6} - x^{7} 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} x^{4} d x - \int_{0}^{1} 3 x^{5} d x + \int_{0}^{1} 3 x^{6} d x - \int_{0}^{1} x^{7} d x

\int_{0}^{1} x^{4} d x = \frac{1}{5}

\int_{0}^{1} 3 x^{5} d x = \frac{1}{2}

\int_{0}^{1} 3 x^{6} d x = \frac{3}{7}

\int_{0}^{1} x^{7} d x = \frac{1}{8}

= \frac{1}{5} - \frac{1}{2} + \frac{3}{7} - \frac{1}{8}

Vereinfache

\frac{1}{5} - \frac{1}{2} + \frac{3}{7} - \frac{1}{8} : \frac{1}{280}

= \frac{1}{280}
