9.814500.05091=36.2925x^2

解答

9.81 \cdot 450 \cdot 0.05091 = 36.2925 x^{2}

解答

x = \frac{3 554919}{10 8065}, x = - \frac{3 554919}{10 8065}

+1

十进制

x = 2.48847 \dots, x = - 2.48847 \dots

求解步骤

9.81 \cdot 450 \cdot 0.05091 = 36.2925 x^{2}

交换两边

36.2925 x^{2} = 9.81 \cdot 450 \cdot 0.05091

数字相乘:

9.81 \cdot 450 \cdot 0.05091 = 224.742195

36.2925 x^{2} = 224.742195

两边除以

36.2925

x^{2} = \frac{224.742195}{36.2925}

对于

x^{2} = f (a)

解为

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

x = \frac{224.742195}{36.2925}, x = - \frac{224.742195}{36.2925}

\frac{224.742195}{36.2925} = \frac{3 554919}{10 8065}

- \frac{224.742195}{36.2925} = - \frac{3 554919}{10 8065}

x = \frac{3 554919}{10 8065}, x = - \frac{3 554919}{10 8065}
