Schritte zur Lösung

X^{3} = 8

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 = 38, X = 38 \frac{- 1 + 3 i}{2}, X = 38 \frac{- 1 - 3 i}{2}

38 = 2

Vereinfache

38 \frac{- 1 + 3 i}{2} : - 1 + 3 i

Vereinfache

38 \frac{- 1 - 3 i}{2} : - 1 - 3 i

X = 2, X = - 1 + 3 i, X = - 1 - 3 i

x^{3} - 3 x^{2} - 9 x = - 27

t^{4} - 4 t^{2} + 3 = 0

x^{3} - x^{2} - 4 x - 6 = 0

25 x^{4} = 74 x^{2} - 49

x^{4} - 3 x^{3} + 6 x^{2} - 12 x + 8 = 0
