log x/0.5 =0.2求x是多少?

log(0.1)log(0.2)log(0.5)(1/根号5次2）=x,求x的值 log x+3下标 （X^3+X-2)/X =2 求 X是多少? [( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4) log25(2x)-log 5(8)=0 解方程求x是多少? 一道高一数学题：解方程：log(0.5x)(2)-log(0.5x^3)(X^2)=log(0.5x^3)(4) 求大神 2 log(3x)= log 4 +log(6-x)怎么求...急 数学log题x是多少. 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x log 8下标 （X-6）+ log 8小标 （x+6)=2 求X y=log(5)x y=ln(0.5x) 求x log₂log₃log₄ X=log₃log₄logS
