\frac{( 2 a ^{2} b ^{4} - a ^{4} b ) ^{3}}{8}

a^{6} b^{12} - \frac{3 a ^{8} b ^{9}}{2} + \frac{3 a ^{10} b ^{6}}{4} - \frac{a ^{12} b ^{3}}{8}

Schritte zur Lösung

\frac{( 2 a ^{2} b ^{4} - a ^{4} b ) ^{3}}{8}

(2 a^{2} b^{4} - a^{4} b)^{3} = 8 a^{6} b^{12} - 12 a^{8} b^{9} + 6 a^{10} b^{6} - a^{12} b^{3}

= \frac{8 a ^{6} b ^{12} - 12 a ^{8} b ^{9} + 6 a ^{10} b ^{6} - a ^{12} b ^{3}}{8}

Wende Bruchregel an:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{8 a ^{6} b ^{12} - 12 a ^{8} b ^{9} + 6 a ^{10} b ^{6} - a ^{12} b ^{3}}{8} = \frac{8 a ^{6} b ^{12}}{8} - \frac{12 a ^{8} b ^{9}}{8} + \frac{6 a ^{10} b ^{6}}{8} - \frac{a ^{12} b ^{3}}{8}

= \frac{8 a ^{6} b ^{12}}{8} - \frac{12 a ^{8} b ^{9}}{8} + \frac{6 a ^{10} b ^{6}}{8} - \frac{a ^{12} b ^{3}}{8}
