log4(log5 a)=log3(log5 b)=1,求a/b.
log4(log5 a)=log3(log5 b)=1,求a/b.
log4(log5 a)=log3(log5 b)=1,求a/b.
log4(log5 a)=1 log5 a =4 a=5^4=625
同理,b=5^3
所以a/b=5
log5[log4(log3 81)]=0
log4(log5 a)=log3(log5 b)=1,求a/b.
如果log3〔log4（log5^a）〕=log4〔log3（log5^b）〕=0,则a/b的值为?
若log5底(log4底(log3底a) )=0,则a=?
log3^10=a,log5^25=b,求log4^45请写出详解 log3^10即log3为底10的对数
2007*log5(1)+log4(27)*log3(4)
若log3 4×log4 5×log5 m=2,则m=
log2(3)*log3(4)*log4(5)*log5(6)*log6(7)*log7(8)=?
化简:1/log3(x)+1/log4(x)+1/log5(x)=
(log4 3+log8 3)(log3 5+log9 5)(log5 2+log25 2)=
计算:log3 4·log4 5·log5 6…log80 81=
当log3^4 *log4^5 *log5^m =2 ,则m为
log3(4)*log4(5)*log5(6)*...*log80(81)
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
比较log3 4与log5 6 大小还有log3 4与log4 5 的大小 看我做的 我用作商法 log4 5 ÷log3 4 =log4 5×log4 3 =log4 8=3÷2＞1 ∴log4 5大于log3 4 帮忙看看错在哪里
已知log2[log4(log3x)]=log3[log5(log2y)]=0,求4更号x-y^1/5
若log3^5 log5^7 log7^x=log4^2 log6^4 log8^6,求x=?
