1.已知log2底[log3底(log4底x)]=0,则x=______.
2.已知2log3底×(x-y)/2=log3底(xy),则x/y=_______.
3.a>0且a≠1时,loga底1+loga底a=_______.
4.a>0且a≠1时,loga底a^2-a^(loga底3)=_____.
5.已知6^a=8,则log6底2=________.
6.已知log5底(log4底a)=1,求实数a的值.
7.2^(2log2底5)=_______.
8.2^(-log2底3)=________.

1.已知log2底[log3底(log4底x)]=0,则x=_64_.
(令[log3底(log4底x)]=1,令log4底x=3)
2.已知2log3底×(x-y)/2=log3底(xy),则x/y=_______. 第二题没看明白
3.a>0且a≠1时,loga底1+loga底a=__1___.
4.a>0且a≠1时,loga底a^2-a^(loga底3)=_2-3__=_-1_.
5.已知6^a=8,则log6底2=___a/3_____.（a=log6底8=3*log6底2）
6.已知log5底(log4底a)=1,求实数a的值.(写过程)
由已知,log4底a=5,所以a=4的5次方,也就是1024
7.2^(2log2底5)=__25__.(写过程)
2log2底5=log2底25
8.2^(-log2底3)=___1/3_____.(写过程)
(-log2底3)=log2底（1/3）

若log4底[log3底(log2底x)]=0,则x=? 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^x)=log3^(log4^y)=0则x+y= 若log2[log3(log4)]=0,求x 已知log3[log4（log2x）]=0，则x=______． log2[log3(log4x)]=log3[log4(log2y)]=0求x+y的值, 已知log2[log4(log3x)]=log3[log5(log2y)]=0,求4更号x-y^1/5 若log2【log3(log4 x)]=0,求x的值若LOG4[LOG3(LOG2(X)]=0,求X的值 log4(log2^x)=log2(log4^x)求log2^x
