解出log 2 x = 2/x -2 X的值，要过程~
log.x = 2x^-1 - 2x
<=>
log.x^2 = log.x^-2 - log.x^2
怎么来的？
log.x = 2x^-1 - 2x
<=>
log.x^2 = log.x^-2 - log.x^2
怎么来的？
我把句点"."当作以2为底算了，还有"^"表示次，比如2^3表示2的3次方，不然不便表达：
log.x = 2/x - 2x
<=>
log.x = 2x^-1 - 2x
<=>
log.x^2 = log.x^-2 - log.x^2
<=>
log.x^2 = log.x^0
<=>
x^2 = x^0 = 1
<=>
x = 1
