v^3=26

解

v^{3} = 26

v = 326, v = - 326 \frac{1}{2} + 326 \frac{3}{2} i, v = - 326 \frac{1}{2} - 326 \frac{3}{2} i

解答ステップ

v^{3} = 26

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}

v = 326, v = 326 \frac{- 1 + 3 i}{2}, v = 326 \frac{- 1 - 3 i}{2}

簡素化

326 \frac{- 1 + 3 i}{2} : - 326 \frac{1}{2} + 326 \frac{3}{2} i

簡素化

326 \frac{- 1 - 3 i}{2} : - 326 \frac{1}{2} - 326 \frac{3}{2} i

v = 326, v = - 326 \frac{1}{2} + 326 \frac{3}{2} i, v = - 326 \frac{1}{2} - 326 \frac{3}{2} i
