x^2= 65/49

解

x^{2} = \frac{65}{49}

x = \frac{65}{7}, x = - \frac{65}{7}

十進法表記

x = 1.15175 \dots, x = - 1.15175 \dots

解答ステップ

x^{2} = \frac{65}{49}

x^{2} = f (a)

の場合, 解は

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

x = \frac{65}{49}, x = - \frac{65}{49}

\frac{65}{49} = \frac{65}{7}

- \frac{65}{49} = - \frac{65}{7}

x = \frac{65}{7}, x = - \frac{65}{7}
