log2[log3(log4x)]=log3[log4(log2y)]=0,则x+y=______.
log2[log3(log4x)]=log3[log4(log2y)]=0,则x+y=______.
若log2(log3(log4x)=log3(log4(log2y)=log4(log2(log3z)=0则x+y-z=
已知log2[log3(log4x)]=log3[log4(log2y)]=0,求x+y
log2[log3(log4x)]=log3[log4(log2y)]=0求x+y的值,
已知log2(log3(log4x))=0,且log4(log2y)=1.求根号x*y^3/4的值在线等啊.
已知log2[log4(log3x)]=log3[log5(log2y)]=0,求4更号x-y^1/5
log2^(log3^x)=log3^(log4^y)=0则x+y=
已知log2[log3(log4x)]=0,求x的值
log2[log3(log4x)]=0求解x值.麻烦写在纸上拍给我.
已知log3[log4(log2x)]=0,则x=______.
若log2[log3(log4)]=0,求x
方程log2[log3(log4(x))]=0的解集为?
