y^2-1/9 =0

解

y^{2} - \frac{1}{9} = 0

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

十進法表記

y = 0.33333 \dots, y = - 0.33333 \dots

解答ステップ

y^{2} - \frac{1}{9} = 0

\frac{1}{9}

を右側に移動します

y^{2} = \frac{1}{9}

x^{2} = f (a)

の場合, 解は

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

y = \frac{1}{9}, y = - \frac{1}{9}

\frac{1}{9} = \frac{1}{3}

- \frac{1}{9} = - \frac{1}{3}

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