x^2=(-1)/3

解

x^{2} = \frac{- 1}{3}

x = \frac{1}{3} i, x = - \frac{1}{3} i

解答ステップ

x^{2} = \frac{- 1}{3}

分数の規則を適用する:

\frac{- a}{b} = - \frac{a}{b}

x^{2} = - \frac{1}{3}

x^{2} = f (a)

の場合, 解は

x = f (a), - f (a)

x = - \frac{1}{3}, x = - - \frac{1}{3}

- \frac{1}{3} = \frac{1}{3} i

- - \frac{1}{3} = - \frac{1}{3} i

x = \frac{1}{3} i, x = - \frac{1}{3} i
