解答
log1/3 2=lg2/lg1/3=-lg2/lg3
log3 1/2=lg3/lg1/2=-lg3/lg2
lg2/lg3-lg3/lg2
∴log1/3 2>log3 1/2,
推荐
- a=log1/3 (1/2),b=log1/2(2/3),c=log3(4/3),比较a,b,c 的大小
- log3 2,1.3^0.2,log1/2 1.3,比较大小
- 设a=log1/3 （1/2）,b=log1/3（2/3）,c=log3（4/3）,则a,b,c的大小关系是
- 设a=log1/3 2/1 b=log1/2 2/3 c=log3 4/3则abc的大小关系
- x=(log1/2底1/3)^-1+(log1/5底1/3)^-1为什么=log3(2)+log3(5)
