d^3=27

Lösung

d^{3} = 27

d = 3, d = - \frac{3}{2} + \frac{3 3}{2} i, d = - \frac{3}{2} - \frac{3 3}{2} i

Schritte zur Lösung

d^{3} = 27

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}

d = 327, d = 327 \frac{- 1 + 3 i}{2}, d = 327 \frac{- 1 - 3 i}{2}

327 = 3

Vereinfache

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

Vereinfache

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

d = 3, d = - \frac{3}{2} + \frac{3 3}{2} i, d = - \frac{3}{2} - \frac{3 3}{2} i

x^{5} - x + 1 = 0
