设a>b>1,log(a)b+log(b)a=10/3,则log(a)b-log(b)a= 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 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. 设a>b>1,且loga(b)+log(b)a=10/3,求loga(b)-log(b)a 求证 log(a)^(b)=1/log(b)^(a)求证 log(a)^(b)=1/log(b)^(a) 若a²>b>a>1,试比较log b b/a ,log b a,log a b的大小 设a、b满足条件a>b>1,3log(a)(b)+3log(b)(a)=10,求式子log(a)(b)+log(b)(a)的值拜托各位了 3Q 一道高一下关于对数的证明题求解设2log b(x)=log a(x)+log c(x),其中x≠1,b^2=ac,求证：log b(a)·log b(c)=1 设log(2)(3)=a,log(3)(7)=b,以a,b表示log(21)(56) 已知a＜b＜1,log(a)b+log(b)a=10/3,求log(a)b-log(b)a的值括号为下标, 已知01,则下列不等式中成立的是（ ）A.log(b)(1/b)＜log(a)(b)＜log(a)(1/b)B.log(a)(b)＜log(b)(1/b)＜log(a)(1/b)C.log(a)(b)＜log(a)(1/b)＜log(b)(1/b)D.log(b)(1/b)＜log(a)(1/b)＜log(a)(b) log(a) (b ) 与log(b) (a)是什么关系 公式：log(a)(b)*log(b)(a)=? 2^(log(a)(b))*8^(log(a)(b)) 证明：log(A)M=log(b)M/log(b)A (b>0且b≠1）. log(a)(b)=log(c)(b) /log(c)(a) 怎么证log(a)(b)=log(c)(b) /log(c)(a)怎么证
