Wende die Summenregel an:

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

= 40 (\int 78125 x^{63} d x - \int 1203125 x^{55} d x + \int 7940625 x^{47} d x - \int 29115625 x^{39} d x + \int 64054375 x^{31} d x - \int 84551775 x^{23} d x + \int 62004635 x^{15} d x - \int 19487171 x^{7} d x)

\int 78125 x^{63} d x = \frac{78125 x ^{64}}{64}

\int 1203125 x^{55} d x = \frac{171875 x ^{56}}{8}

\int 7940625 x^{47} d x = \frac{2646875 x ^{48}}{16}

\int 29115625 x^{39} d x = \frac{5823125 x ^{40}}{8}

\int 64054375 x^{31} d x = \frac{64054375 x ^{32}}{32}

\int 84551775 x^{23} d x = \frac{28183925 x ^{24}}{8}

\int 62004635 x^{15} d x = \frac{62004635 x ^{16}}{16}

\int 19487171 x^{7} d x = \frac{19487171 x ^{8}}{8}

= 40 (\frac{78125 x ^{64}}{64} - \frac{171875 x ^{56}}{8} + \frac{2646875 x ^{48}}{16} - \frac{5823125 x ^{40}}{8} + \frac{64054375 x ^{32}}{32} - \frac{28183925 x ^{24}}{8} + \frac{62004635 x ^{16}}{16} - \frac{19487171 x ^{8}}{8})
