若log3[log4(log5a)]=log4[log3(log5b)]=0,则a/b等于若log3[log4(log5a)]=log4[log3(log5b)]=0,则a/b等于若log3[log4
若log3[log4(log5a)]=log4[log3(log5b)]=0,则a/b等于
若log3[log4(log5a)]=log4[log3(log5b)]=0,则a/b等于
若log3[log4(log5a)]=log4[log3(log5b)]=0,则a/b等于
log3[log4(log5a)]=log4[log3(log5b)]=0
那么,对于log3[log4(log5a)]=0
有 log4(log5a)=1
因此 log5a=4
a=5^4
对于 log4[log3(log5b)]=0
有 log3(log5b)=1
因此 log5b=3
b=5^3
于是 a/b=5^4/5^3=5
log3[log3(log5a)]=0 log3(log5a)=1 log5a=3 a=625 log4[log4(log5b)]=0 log4(log5b)=1 log5b=4 b=125 所以 a/b=625/125=5 ..
若log3[log4(log5a)]=log4[log3(log5b)]=0,则a/b等于
log3[log4(log5a)]=log4[log3(log5b)]=0求a/b等于几?
若log3【log4(log2x)】=0,则x=
若log2[log3(log4)]=0,求x
若log3 4*log4 8*log8 m=log4 16求m
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
若log3(4)×log4(8)×log8(m)=log4(16).则m等于?谢谢
log3(4)×log4(3)×log3(m)=log4(16)过程~~~~谢谢了
若a=log2 3,b=log3 2,c=log4 6比较大小
若log3(7)*log2(9)*log49(a)=log4(1/2),则a=?
若log4底[log3底(log2底x)]=0,则x=?
若log5底(log4底(log3底a) )=0,则a=?
若log3 4×log4 5×log5 m=2,则m=
若log3(x)=-1/log4(3),则x+x^2+.+x^n+.=
