(5 x + 4) (5 x^{2} + 8 x)^{4} : 3125 x^{9} + 22500 x^{8} + 64000 x^{7} + 89600 x^{6} + 61440 x^{5} + 16384 x^{4}

= \int 3125 x^{9} + 22500 x^{8} + 64000 x^{7} + 89600 x^{6} + 61440 x^{5} + 16384 x^{4} 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 3125 x^{9} d x + \int 22500 x^{8} d x + \int 64000 x^{7} d x + \int 89600 x^{6} d x + \int 61440 x^{5} d x + \int 16384 x^{4} d x

\int 3125 x^{9} d x = \frac{625 x ^{10}}{2}

\int 22500 x^{8} d x = 2500 x^{9}

\int 64000 x^{7} d x = 8000 x^{8}

\int 89600 x^{6} d x = 12800 x^{7}

\int 61440 x^{5} d x = 10240 x^{6}

\int 16384 x^{4} d x = \frac{16384 x ^{5}}{5}

= \frac{625 x ^{10}}{2} + 2500 x^{9} + 8000 x^{8} + 12800 x^{7} + 10240 x^{6} + \frac{16384 x ^{5}}{5}
