m^3=5

解

m^{3} = 5

m = 35, m = - 35 \frac{1}{2} + 35 \frac{3}{2} i, m = - 35 \frac{1}{2} - 35 \frac{3}{2} i

解答ステップ

m^{3} = 5

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}

m = 35, m = 35 \frac{- 1 + 3 i}{2}, m = 35 \frac{- 1 - 3 i}{2}

簡素化

35 \frac{- 1 + 3 i}{2} : - 35 \frac{1}{2} + 35 \frac{3}{2} i

簡素化

35 \frac{- 1 - 3 i}{2} : - 35 \frac{1}{2} - 35 \frac{3}{2} i

m = 35, m = - 35 \frac{1}{2} + 35 \frac{3}{2} i, m = - 35 \frac{1}{2} - 35 \frac{3}{2} i
