F^2=10^2+10^2+21010*1/2

解

F^{2} = 1 0^{2} + 1 0^{2} + 2 \cdot 10 \cdot 10 \cdot \frac{1}{2}

F = 103, F = - 103

十進法表記

F = 17.32050 \dots, F = - 17.32050 \dots

解答ステップ

F^{2} = 1 0^{2} + 1 0^{2} + 2 \cdot 10 \cdot 10 \cdot \frac{1}{2}

簡素化

1 0^{2} + 1 0^{2} + 2 \cdot 10 \cdot 10 \cdot \frac{1}{2} : 300

x^{2} = f (a)

の場合, 解は

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

F = 300, F = - 300

300 = 103

- 300 = - 103

F = 103, F = - 103
