设a>1,则log(0.2)a,0.2的a次方,a的0.2次方的大小关系是设a>1,则log(0.2)a,0.2的a次方,a的0.2次方的大小关系是设a>1,则log(0.2)a,0.2的a次方,a的

设a>1,则log(0.2)a,0.2的a次方,a的0.2次方的大小关系是
设a>1,则log(0.2)a,0.2的a次方,a的0.2次方的大小关系是

设a>1,则log(0.2)a,0.2的a次方,a的0.2次方的大小关系是
因为log(0.2)a ,0.2的a次方两个函数互为反函数,画图可知,当a>1时,0

设a>1,则log(0.2)a,0.2的a次方,a的0.2次方的大小关系是 设a>b>1,log(a)b+log(b)a=10/3,则log(a)b-log(b)a= 设A=LOG(0.5 )3,B=(1/3 )0.2 ,比较A,B的大小 设a=log(1/3)1/2 b=log(1/3)2/3 c=log(3)4/3 则abc的大小 关系是? 设a>0且a≠1,log a (xy)=√3,log a (ax)=3,则log a y=_____ 1、若lg2=a,lg3=b,则lg√15=?(用a、b表达)2、若log(15)(5)=m,则log(15)(3)=(用m表示)3、log(2)(3)*log(3)(4)*log(4)(5)*log(5)(6)*log(6)(7)*log(7)(8)=?4、设log(3)(2)=log(2)(3^x),x=?这个对数函数我学的很不好,所以希望过 设a=(1/2)^0.5 b=0.3^0.5 c=log(0.3)0.2 则abc的大小关系是 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 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 设log√3 2=1-a/a则log12 3=设log√3 2=1-a/a则log12 3= 第八题 设log(a)(x+y)=根号三,log(a)x=1,求log(a)y 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a=log底数0.2真数2,b=log底数0.2真数3,c=2的0.2次数,d=0.2²比较大小 【高二数学】设a>0且a≠1,函数f(x)=log a (x²-2x+3)有最小值,则不等式log a (x-1)>0的解集为设a>0且a≠1,函数f(x)=log a (x²-2x+3)有最小值,则不等式log a (x-1)>0的解集为___________.【说明:log a (x 设a∈(0,1/2),则a的a次方,log(1/2)a,a的1/2次方 的大小关系是? 设a=1/log(4)3+1/log(7)3,求证a属于(3,4) 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) 对数的运算问题-log a 1/x=-(log a 1-log a x)=log a x
