b^3=44

解

b^{3} = 44

b = 344, b = - 344 \frac{1}{2} + 344 \frac{3}{2} i, b = - 344 \frac{1}{2} - 344 \frac{3}{2} i

解答ステップ

b^{3} = 44

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}

b = 344, b = 344 \frac{- 1 + 3 i}{2}, b = 344 \frac{- 1 - 3 i}{2}

簡素化

344 \frac{- 1 + 3 i}{2} : - 344 \frac{1}{2} + 344 \frac{3}{2} i

簡素化

344 \frac{- 1 - 3 i}{2} : - 344 \frac{1}{2} - 344 \frac{3}{2} i

b = 344, b = - 344 \frac{1}{2} + 344 \frac{3}{2} i, b = - 344 \frac{1}{2} - 344 \frac{3}{2} i
