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) 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. 若| log a 1/4 |=log a 1/4 ,| log b a |=-log b a 则 a b满足什么条件0＜a＜1 b＞1log旁边的a在下面 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 求证 log(a)^(b)=1/log(b)^(a)求证 log(a)^(b)=1/log(b)^(a) 已知log（底数二分之一）b＜-log（底数2）a＜-2log（底数4）c ,则a b c 的关系为 已知 log (a) ab=1/p ,则 log (ab) a/b=__ __. 关于数学对数的换底公式推论的问题已知 log(2)(3) = a,log(3(7)=b,用a,b表示log(42)(56)因为log(2)(3)=a,则1/a=log(3)(2),又∵log(3)(7)=b,∴log(42)(56)=log(3)(56)/log(3)(42)=log(3)(7)+3·log(3)(2)/log(3)(7)+log(3)(2)+1=ab+3/ab+b+1 关于数学对数的换底公式推论的问题已知 log(2)(3) = a,log(3(7)=b,用a,b表示log(42)(56)因为log(2)(3)=a,则1/a=log(3)(2),又∵log(3)(7)=b,∴log(42)(56)=log(3)(56)/log(3)(42)=log(3)(7)+3·log(3)(2)/log(3)(7)+log(3)(2)+1=ab+3/ab+b+1 若a²>b>a>1,试比较log b b/a ,log b a,log a b的大小 已知log a x=2,log b x=1,log c x=4,求log abc x 的值 已知log(a)x=1,log(b)x=2,log(c)x=4,则log(abc)x=? 已知a=log(2)3+log(2)√3,b=log(2)9-log(2)√3,c=log(3)2,则a,b,c的大小关系是（详细过程,）A.a=b＜c B.a=b＞c C.a＜b＜c D.a＞b＞c Log(2)1/25•log(3)1/8•log(5)1/9化简 还有已知log(18)9=a,log(18)5=b求log(36)45 值 设a>b>1,log(a)b+log(b)a=10/3,则log(a)b-log(b)a=
