求解一道log题log8（x+1）=2/3 求x

（高一）若x满足2(log(1/2)x)^2-14log(4)x+3≤0,求f(x)=[log(2)(x/2)]*{lo 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x 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 设A={x|2(log1/2^x)^2-21*log8^x+3≤0}若当x∈A时f（x）=log2 ^2^x/a*log 1/log（2）x+1/log（3）x+1/log（4）x=1,x=? log(0.1)log(0.2)log(0.5)(1/根号5次2）=x,求x的值 2 log(3x)= log 4 +log(6-x)怎么求...急 求函数y=log+2的x次方+1/log（3x-2）的定义域 已知log∨7∧[log∨3∧（log∨2∧x）]=0 求X∧1/2的值 x=log7 1/3 x=log8 7 求x 顺便问一下,类似这样的对数怎么求 [( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X log 8下标 （X-6）+ log 8小标 （x+6)=2 求X
