0.5^2+0.5^2=x^2

解

0. 5^{2} + 0. 5^{2} = x^{2}

解

x = \frac{1}{2}, x = - \frac{1}{2}

+1

十進法表記

x = 0.70710 \dots, x = - 0.70710 \dots

解答ステップ

0. 5^{2} + 0. 5^{2} = x^{2}

辺を交換する

x^{2} = 0. 5^{2} + 0. 5^{2}

簡素化

0. 5^{2} + 0. 5^{2} : 0.5

x^{2} = f (a)

の場合, 解は

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

x = 0.5, x = - 0.5

0.5 = \frac{1}{2}

- 0.5 = - \frac{1}{2}

x = \frac{1}{2}, x = - \frac{1}{2}
