v^2=0+22.115.84

解

v^{2} = 0 + 2 \cdot 2.11 \cdot 5.84

v = \frac{15403}{25}, v = - \frac{15403}{25}

十進法表記

v = 4.96435 \dots, v = - 4.96435 \dots

解答ステップ

v^{2} = 0 + 2 \cdot 2.11 \cdot 5.84

簡素化

0 + 2 \cdot 2.11 \cdot 5.84 : 24.6448

x^{2} = f (a)

の場合, 解は

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

v = 24.6448, v = - 24.6448

24.6448 = \frac{15403}{25}

- 24.6448 = - \frac{15403}{25}

v = \frac{15403}{25}, v = - \frac{15403}{25}
