log(a) (b ) 与log(b) (a)是什么关系

log(a) (b ) 与log(b) (a)是什么关系 27-1/ 若a>0,b>0,a*b>1,log(1/2)[a]=ln2,则log(a)[b]与log(1/2)[a]的关系是：（）?(A)log(a)b< log(1/2)[a](B)log(a)b= log(1/2)[a](C)log(a)b>log(1/2)[a](D)log(a)b与log(1/2)[a] 无法比较大小我做到一半就做不下去了：a=(1/2)^(ln2)log 1≤a≤b≤c,证明log(a)(b)+log(b)(c)+log(c)(a)≤log(b)(a)+log(c)(b)+log(a)(c) 化简log(1/a)b+log(a)b 公式：log(a)(b)*log(b)(a)=? 2^(log(a)(b))*8^(log(a)(b)) log(a)(b)=log(c)(b) /log(c)(a) 怎么证log(a)(b)=log(c)(b) /log(c)(a)怎么证 已知01比较log(a)(1/b),log(a)(b),log(b)(1/b)的大小 已知01.比较log a 1/b,log a b,log b 1/b的大小. 求证 log(a)^(b)=1/log(b)^(a)求证 log(a)^(b)=1/log(b)^(a) log(a)(b)+log(a)(c)可以等于什么 matlab中合并对数?如何实现log(a)-log(b)=log(a/b) 证明log^a+log^b=log^(a+b)要过程 log(a)b=log(c)b/log(c)a 是怎么推算来的 a^[log(a)b×log(b)c×log(c)N]求值 求对数的解答题!求值.log(b)A*log(c)B*log(a)C 请问：LOG(B)A * LOG(A)B=?答案跟过程!谢谢其中(B)与(A)是下标 2log(b)x=log(a)x+log(c)x求证,c^2=(ac)^[log(a)b]
