7

\frac{7 x ^{3}}{7} = \frac{19}{7}

x^{3} = \frac{19}{7}

Für

x^{3} = f (a)

sind die Lösungen

x = 3 f (a), 3 f (a) \frac{- 1 - 3 i}{2}, 3 f (a) \frac{- 1 + 3 i}{2}

x = 3 \frac{19}{7}, x = 3 \frac{19}{7} \frac{- 1 + 3 i}{2}, x = 3 \frac{19}{7} \frac{- 1 - 3 i}{2}

Vereinfache

3 \frac{19}{7} \frac{- 1 + 3 i}{2} : - 3 \frac{19}{7} \frac{1}{2} + 3 \frac{19}{7} \frac{3}{2} i
