求一log题20=X/log(1100/33),请问X是多少?写错了，应该是20=X/2log(1100/33)

[( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X log₂log₃log₄ X=log₃log₄logS 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x 2 log(3x)= log 4 +log(6-x)怎么求...急 （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 log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4) solve:log(x)+log(2x)=2 log(X+5)+log(X+2)=1 x=log a 2 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 2log(b)x=log(a)x+log(c)x 数学log题x是多少.
