1000.055^2=0.0038v^2

解答

100 \cdot 0.05 5^{2} = 0.0038 \cdot v^{2}

解答

v = \frac{55}{38}, v = - \frac{55}{38}

+1

十进制

v = 8.92217 \dots, v = - 8.92217 \dots

求解步骤

100 \cdot 0.05 5^{2} = 0.0038 v^{2}

交换两边

0.0038 v^{2} = 100 \cdot 0.05 5^{2}

0.05 5^{2} = 0.003025

0.0038 v^{2} = 100 \cdot 0.003025

数字相乘:

100 \cdot 0.003025 = 0.3025

0.0038 v^{2} = 0.3025

两边除以

0.0038

v^{2} = \frac{0.3025}{0.0038}

对于

x^{2} = f (a)

解为

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

v = \frac{0.3025}{0.0038}, v = - \frac{0.3025}{0.0038}

\frac{0.3025}{0.0038} = \frac{55}{38}

- \frac{0.3025}{0.0038} = - \frac{55}{38}

v = \frac{55}{38}, v = - \frac{55}{38}
