若log3【log4(log2x)】=0,则x=

若log3【log4(log2x)】=0,则x= log4[log3(log2x)]=0,求x^-1/2 若log3[log4(log5a)]=log4[log3(log5b)]=0,则a/b等于 若log2[log3(log4)]=0,求x log3 (log4 x)=0 对数方程, log5[log4(log3 81)]=0 已知log3【log3(log2x)】=0,则x=（ ）, log3[log4(log5a)]=log4[log3(log5b)]=0求a/b等于几? 若log4底[log3底(log2底x)]=0,则x=? 若log5底(log4底(log3底a) )=0,则a=? 若log2【log3(log4 x)]=0,求x的值 若LOG4[LOG3(LOG2(X)]=0,求X的值 解方程log3(log4(x)）=0 已知log7[log3(log2x)]=0,则x= 已知log7[log3(log2x)]=0,那么x1/2等于 log3[log5(log2x)]=0 求x的值 若log3 4*log4 8*log8 m=log4 16求m 若函数y=log4(2-log2x)的值域是（-∞,0）,那么它的定义域是
