m^3=0.027

Lösung

m^{3} = 0.027

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

Schritte zur Lösung

m^{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}

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

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

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

15 x^{4} + 240 x^{2} + 225 = 0

2 x^{3} = 4 x^{2} - 2 x

1 - 3 (x - 4)^{3} = 25

4 x^{3} = 92
