(x+1)^3=8

Lösung

(x + 1)^{3} = 8

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

Schritte zur Lösung

(x + 1)^{3} = 8

Für

g^{3} (x) = f (a)

sind die Lösungen

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

Löse

x + 1 = 38 : x = 1

Löse

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

Löse

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

Die Lösungen sind

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

(z^{2} + 5)^{3} = 0
