c^3=49

解

c^{3} = 49

c = 349, c = - 349 \frac{1}{2} + 349 \frac{3}{2} i, c = - 349 \frac{1}{2} - 349 \frac{3}{2} i

解答ステップ

c^{3} = 49

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 = 349, c = 349 \frac{- 1 + 3 i}{2}, c = 349 \frac{- 1 - 3 i}{2}

簡素化

349 \frac{- 1 + 3 i}{2} : - 349 \frac{1}{2} + 349 \frac{3}{2} i

簡素化

349 \frac{- 1 - 3 i}{2} : - 349 \frac{1}{2} - 349 \frac{3}{2} i

c = 349, c = - 349 \frac{1}{2} + 349 \frac{3}{2} i, c = - 349 \frac{1}{2} - 349 \frac{3}{2} i
