x^3=-0.027

Lösung

x^{3} = - 0.027

Lösung

x = - \frac{3}{10}, x = \frac{3}{20} - \frac{3 3}{20} i, x = \frac{3}{20} + \frac{3 3}{20} i

Schritte zur Lösung

x^{3} = - 0.027

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 = 3 - 0.027, x = 3 - 0.027 \frac{- 1 + 3 i}{2}, x = 3 - 0.027 \frac{- 1 - 3 i}{2}

3 - 0.027 = - \frac{3}{10}

Vereinfache

3 - 0.027 \frac{- 1 + 3 i}{2} : \frac{3}{20} - \frac{3 3}{20} i

Vereinfache

3 - 0.027 \frac{- 1 - 3 i}{2} : \frac{3}{20} + \frac{3 3}{20} i

x = - \frac{3}{10}, x = \frac{3}{20} - \frac{3 3}{20} i, x = \frac{3}{20} + \frac{3 3}{20} i
