solvefor x,v=d*sqrt(((2e_{0)))/x}

解答

求解

x, v = d \cdot \frac{( 2 e _{0} )}{x}

x = \frac{2 e _{0} d ^{2}}{v ^{2}}

求解步骤

v = d \frac{( 2 e _{0} )}{x}

交换两边

d \frac{2 e _{0}}{x} = v

两边除以

d

\frac{2 e _{0}}{x} = \frac{v}{d}

两边进行平方:

\frac{2 e _{0}}{x} = \frac{v ^{2}}{d ^{2}}

\frac{2 e _{0}}{x} = \frac{v ^{2}}{d ^{2}}

解

\frac{2 e _{0}}{x} = \frac{v ^{2}}{d ^{2}} : x = \frac{2 e _{0} d ^{2}}{v ^{2}}

x = \frac{2 e _{0} d ^{2}}{v ^{2}}

so l v e f or x, 3 x + y = a

x = 5

x^{\frac{1}{5}} = 4

\frac{( y + 2 )}{( y - 2 )} = \frac{1}{2}

x^{2} + x - 1800 = 0
