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}

r = 327, r = 327 \frac{- 1 + 3 i}{2}, r = 327 \frac{- 1 - 3 i}{2}

327 = 3

Vereinfache

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

r = 3, r = - \frac{3}{2} + \frac{3 3}{2} i, r = - \frac{3}{2} - \frac{3 3}{2} i

28 x^{3} + 16 x^{2} - 80 x = 0

7.8 x^{2} + x^{3} - 0.0317 = 0

x^{5} - 2 x^{4} + x^{3} = 0

735 = 8 (1 + x)^{29}
