Lösung

löse nach

x, x^{3} = 17

x = 317, x = - 317 \frac{1}{2} + 317 \frac{3}{2} i, x = - 317 \frac{1}{2} - 317 \frac{3}{2} i

Schritte zur Lösung

x^{3} = 17

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 = 317, x = 317 \frac{- 1 + 3 i}{2}, x = 317 \frac{- 1 - 3 i}{2}

Vereinfache

317 \frac{- 1 + 3 i}{2} : - 317 \frac{1}{2} + 317 \frac{3}{2} i

Vereinfache

317 \frac{- 1 - 3 i}{2} : - 317 \frac{1}{2} - 317 \frac{3}{2} i

x = 317, x = - 317 \frac{1}{2} + 317 \frac{3}{2} i, x = - 317 \frac{1}{2} - 317 \frac{3}{2} i

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

15 x^{3} + 7 x^{2} - 7 x + 1 = 0

4 a^{4} + 28 a^{2} + 48 = 0

x^{3} + 5 x^{2} = x + 5

y^{3} + 2 y^{2} + 4 y + 2 = 0
