改良

y^{8} = - 2

解く

y^{8} = - 2 : y = \frac{1}{2 ^{\frac{5}{8}} 2 - 1} + \frac{2 - 1}{2 ^{\frac{5}{8}}} i, y = - \frac{1}{2 ^{\frac{5}{4}} \cdot \frac{2 - 1}{2 ^{\frac{5}{8}}}} - \frac{2 - 1}{2 ^{\frac{5}{8}}} i, y = - \frac{1}{2 ^{\frac{5}{8}} 1 + 2} + \frac{1 + 2}{2 ^{\frac{5}{8}}} i, y = \frac{1}{2 ^{\frac{5}{8}} 1 + 2} - \frac{1 + 2}{2 ^{\frac{5}{8}}} i, y = \frac{1}{2 ^{\frac{5}{8}} 1 + 2} + \frac{1 + 2}{2 ^{\frac{5}{8}}} i, y = - \frac{1}{2 ^{\frac{5}{4}} \cdot \frac{1 + 2}{2 ^{\frac{5}{8}}}} - \frac{1 + 2}{2 ^{\frac{5}{8}}} i, y = - \frac{1}{2 ^{\frac{5}{8}} 2 - 1} + \frac{2 - 1}{2 ^{\frac{5}{8}}} i, y = \frac{1}{2 ^{\frac{5}{8}} 2 - 1} - \frac{2 - 1}{2 ^{\frac{5}{8}}} i
