x^3= 8/(11^3)

Lösung

x^{3} = \frac{8}{1 1 ^{3}}

x = \frac{2}{11}, x = - \frac{1}{11} + \frac{3}{11} i, x = - \frac{1}{11} - \frac{3}{11} i

Schritte zur Lösung

x^{3} = \frac{8}{1 1 ^{3}}

1 1^{3} = 1331

x^{3} = \frac{8}{1331}

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 \frac{8}{1331}, x = 3 \frac{8}{1331} \frac{- 1 + 3 i}{2}, x = 3 \frac{8}{1331} \frac{- 1 - 3 i}{2}

3 \frac{8}{1331} = \frac{2}{11}

Vereinfache

3 \frac{8}{1331} \frac{- 1 + 3 i}{2} : - \frac{1}{11} + \frac{3}{11} i

Vereinfache

3 \frac{8}{1331} \frac{- 1 - 3 i}{2} : - \frac{1}{11} - \frac{3}{11} i

x = \frac{2}{11}, x = - \frac{1}{11} + \frac{3}{11} i, x = - \frac{1}{11} - \frac{3}{11} i

(x + 7)^{3} - 8 = 0

a x^{2} b x + c = 0

(x - 4)^{3} = 729

7 x^{3} - 3 x^{2} - 35 x + 15 = 0

1 - y^{2} = y^{4} - y^{2} + y - 1
