7x^2=1

解

7 x^{2} = 1

解

x = \frac{1}{7}, x = - \frac{1}{7}

+1

十進法表記

x = 0.37796 \dots, x = - 0.37796 \dots

解答ステップ

7 x^{2} = 1

以下で両辺を割る

7

x^{2} = \frac{1}{7}

x^{2} = f (a)

の場合, 解は

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

x = \frac{1}{7}, x = - \frac{1}{7}

\frac{1}{7} = \frac{1}{7}

- \frac{1}{7} = - \frac{1}{7}

x = \frac{1}{7}, x = - \frac{1}{7}
