0.8 m/(s^2)s=2.5u,a=9

解答

0.8 \frac{m}{s ^{2}} s = 2.5 u, a = 9

无解

求解步骤

[0.8 \cdot \frac{m}{s ^{2}} s = 2.5 u a = 9]

解

0.8 \frac{m}{s ^{2}} s = 2.5 u

求得

a = 9 : (a = 9, s = \frac{0.32 m}{u}, u \in R)

将解代入原方程进行验证

无解

x^{2} - x - 3 x + 3 = 0, y^{2} - 3 y + 2 = 0

t^{2} y = 4 t, x = 2

6^{b} = 8 4^{c}, 1 4^{a} = 3

a + b = 4, a \cdot b = 1 a^{3} + b^{3}

3 x - 2 y = 6, x y = 12
