c^3=46

解

c^{3} = 46

c = 346, c = - 346 \frac{1}{2} + 346 \frac{3}{2} i, c = - 346 \frac{1}{2} - 346 \frac{3}{2} i

解答ステップ

c^{3} = 46

x^{3} = f (a)

では, 解は

x = 3 f (a), 3 f (a) \frac{- 1 - 3 i}{2}, 3 f (a) \frac{- 1 + 3 i}{2}

c = 346, c = 346 \frac{- 1 + 3 i}{2}, c = 346 \frac{- 1 - 3 i}{2}

簡素化

346 \frac{- 1 + 3 i}{2} : - 346 \frac{1}{2} + 346 \frac{3}{2} i

簡素化

346 \frac{- 1 - 3 i}{2} : - 346 \frac{1}{2} - 346 \frac{3}{2} i

c = 346, c = - 346 \frac{1}{2} + 346 \frac{3}{2} i, c = - 346 \frac{1}{2} - 346 \frac{3}{2} i
