log3[log4(log5a)]=log4[log3(log5b)]=0求a/b等于几?

log3[log4(log5a)]=log4[log3(log5b)]=0求a/b等于几? 若log3[log4(log5a)]=log4[log3(log5b)]=0,则a/b等于 log6(log4(log3 81)== log3 (log4 x)=0 对数方程, log5[log4(log3 81)]=0 求证log3(4)=1/log4(3) log3(8)/log3(4)=log4(8)吗 为什么 log3（4）×log4（3）×log3（m）=log4（16）过程~~~~谢谢了 设log3（4）*log4(m)=log4(16),求m设log3（4）*log4(m)=log4(16),求m 若log3【log4(log2x)】=0,则x= 已知log3 m=log4 16,则m= 若log2[log3(log4)]=0,求x log4[log3(log2x)]=0,求x^-1/2 log3^x=log4^x求x值 LOG4 SIN3/4π+LOG3 tan(-5/6π)=? 解方程log3(log4(x)）=0 1/(2log3 4）=1/2·log4 log3(4)·log4(8)·log8(m)=log4(16)则m=
