如果log4(log2^x)是表示外面的log以4为底,而里面的log以10或其它数(>0)为底的话,则
log4(log2^x)=[log2(log2^x)]/2=log2(log4^x)=log2(2log2^x)
[log2(log2^x)]/2=log2(2log2^x)
log2(log2^x)=2log2(2log2^x)
log2(log2^x)=log2(4(log2^x)^2)
log2^x=4(log2^x)^2
log2^x=0
或log2^x=1/4

log4(log2^x)=log2(log4^x)求log2^x log2^x=log4^9 log2(x-2)=log4(5-x) log2^x >= log4^(3x+4) 1.log2(x)=log4(x),求x 对数问题 log2^x=log4^9 若log2[log3(log4)]=0,求x log2^x=log4^x,则x= log4(13-3x)=log2(x-1) 求导：y=log2(x) * log4(x)的导数对数方程 log2^(x-1)=log4^x log4 (x+2) = log2 (2x-1)
