log(4)6能不能化简为log(2)3呢? 还有log(3)x=3分之1 x=多少 log(2x)+log(3y)-log(2z) 怎么化简? log3(x^2-2x-6)=2 log(3x+6)=1+l 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(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4) 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x 1/log（2）x+1/log（3）x+1/log（4）x=1,x=? log的数学题2 + log 2（为底）4= 3x-1 已知log(1/7)[log(3)(log(2)x)]=0 log以2为底的（log以3为底的（log以4为底的x))=log以3为底的（log以4为底的（log以2为底的y))= log(9)x+log(x^2)3=1的解为? 2log∨6x=1-log∨6 3,则x的值是什么
