Schritte zur Lösung

x^{3} = 64000

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 = 364000, x = 364000 \frac{- 1 + 3 i}{2}, x = 364000 \frac{- 1 - 3 i}{2}

364000 = 40

Vereinfache

364000 \frac{- 1 + 3 i}{2} : - 20 + 203 i

Vereinfache

364000 \frac{- 1 - 3 i}{2} : - 20 - 203 i

x = 40, x = - 20 + 203 i, x = - 20 - 203 i

2 x^{3} + 5 x^{2} - 12 x = 0

y^{4} + 32 y^{2} - 144 = 0

x^{3} - 5 x^{2} + 12 = 0

10 x^{6} - 25 x^{4} + 28 x^{2} + 9 = 0

(x + 1) (x^{2} + 1) = (x + 1)^{2}
