solvefor x,d= 1/3 x^2t

解答

求解

x, d = \frac{1}{3} x^{2} t

解答

x = \frac{3 d}{t}, x = - \frac{3 d}{t}; t \neq = 0

求解步骤

d = \frac{1}{3} x^{2} t

交换两边

\frac{1}{3} x^{2} t = d

在两边乘以

3

t x^{2} = 3 d

两边除以

t; t \neq = 0

x^{2} = \frac{3 d}{t}; t \neq = 0

对于

x^{2} = f (a)

解为

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

x = \frac{3 d}{t}, x = - \frac{3 d}{t}; t \neq = 0

5.3*10^{-12}=(1*10^{-4}+s)(s)

5.3 \cdot 1 0^{- 12} = (1 \cdot 1 0^{- 4} + s) (s)

q u a d r a t i c f or m u l a x^{2} + x = 9

solvefor x,x^2y-4y=8

so l v e f or x, x^{2} y - 4 y = 8

solvefor B,rs=ro+B/s (ro-rB)(1-Tc)

so l v e f or B, rs = ro + \frac{B}{s} (ro - r B) (1 - T c)
