h^3=0.027

Lösung

h^{3} = 0.027

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

Schritte zur Lösung

h^{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}

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

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

x^{3} - 3 x^{2} - 4 x + 6 = 0

3 y^{6} = 75 y^{4}

so l v e f or x, z = x^{4} - 2 y^{3}

x^{3} = 888

2 x^{3} - 5 x^{2} = 0
