x^2+0.75^2=1^2

解

x^{2} + 0.7 5^{2} = 1^{2}

x = \frac{7}{4}, x = - \frac{7}{4}

十進法表記

x = 0.66143 \dots, x = - 0.66143 \dots

解答ステップ

x^{2} + 0.7 5^{2} = 1^{2}

0.7 5^{2}

を右側に移動します

x^{2} = 0.4375

x^{2} = f (a)

の場合, 解は

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

x = 0.4375, x = - 0.4375

0.4375 = \frac{7}{4}

- 0.4375 = - \frac{7}{4}

x = \frac{7}{4}, x = - \frac{7}{4}
