s^3=729

Lösung

s^{3} = 729

s = 9, s = - \frac{9}{2} + \frac{9 3}{2} i, s = - \frac{9}{2} - \frac{9 3}{2} i

Schritte zur Lösung

s^{3} = 729

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}

s = 3729, s = 3729 \frac{- 1 + 3 i}{2}, s = 3729 \frac{- 1 - 3 i}{2}

3729 = 9

Vereinfache

3729 \frac{- 1 + 3 i}{2} : - \frac{9}{2} + \frac{9 3}{2} i

Vereinfache

3729 \frac{- 1 - 3 i}{2} : - \frac{9}{2} - \frac{9 3}{2} i

s = 9, s = - \frac{9}{2} + \frac{9 3}{2} i, s = - \frac{9}{2} - \frac{9 3}{2} i

x^{3} + 5 x^{2} - 25 x - 125 = 0

t^{3} - 9 t^{2} = 0

x^{3} + 2 x^{2} + 1 = 0

g^{4} - 8 g^{2} + 16 = 0

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