v^3=8

Lösung

v^{3} = 8

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

Schritte zur Lösung

v^{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}

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

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

m^{3} - 64 = 0

3^{3} = (9 x^{3})

x^{3} - 3 x = x

so l v e f or y, x = (y + 2)^{3}

so l v e f or x, f = x^{2} y g x^{2} + 2
