log(2)(x)log(2)(4x)-3log(2)(x)-12=0

已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4) 4^log(4)[x^2]+3^log(9)[6x]=log(2)[16] 2 log(3x)= log 4 +log(6-x)怎么求...急 [( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X 对数计算1.{log(4)（3）+ log(8) (3)} X {log(3)(2)+log(9)(2)}2.{log( 已知log(1/7)[log(3)(log(2)x)]=0 1/log（2）x+1/log（3）x+1/log（4）x=1,x=? 已知log的2次方【log的3次方（log的4次方x)】=log【log的4次方（log的2次方y】=0,求x+y的值 （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 solve:log(x)+log(2x)=2 log(X+5)+log(X+2)=1
