Find the right formula for solving the equation

x^{5} + 32 = 0

.

x_{k} = \sqrt[5]{| - 32 |} (\cos \frac{π + 2 k π}{5} + i \sin \frac{π + 2 k π}{5})

,

k = 0, 1, 2, 3, 4

x_{k} = \sqrt[5]{- 32} (\cos \frac{π + 2 k π}{5} + i \sin \frac{π + 2 k π}{5})

,

k = 0, 1, 2, 3, 4

x_{k} = \sqrt[5]{| - 32 |} (\cos \frac{π + k π}{5} + i \sin \frac{π + k π}{5})

,

k = 0, 1, 2, 3, 4

x_{k} = \sqrt[5]{| - 32 |} (\cos \frac{π + 2 k π}{5} + \sin \frac{π + 2 k π}{5})

,

k = 0, 1, 2, 3, 4
