b=a+1 且a＞0则2log小的3(9b)-log小的3(a²+2a+1)=?

b=a+1 且a＞0则2log小的3(9b)-log小的3(a²+2a+1)=? 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 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 解方程[log(a)(x-1)]-[log(a)(2x-3)]=log(a)(1/3-x),(a＞0,且a≠1). 若a＞0且a≠1,且log a（2a+1）＜log a 3a＜0,求a的取值范围 证明：log(A)M=log(b)M/log(b)A (b>0且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 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 函数y=log(a)^(x+b)+c(a>0且a不等于1)的图像恒过定点(3,2),则实数b,c的值 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 设a>0,且a≠1,b>0且b≠1则log根号a(b)*log根号b(a)= 设a>b>1,且loga(b)+log(b)a=10/3,求loga(b)-log(b)a 已知a^2=m,a^3=n,a＞0且a≠1,求2log a m+log a n 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, 如果a＞0,且a不等于1,M=log(a为底对数是(x^3+1)),N=log(a为底对数为(a^2+1)),则MN的关系? 设a>0且a≠1,log a (xy)=√3,log a (ax)=3,则log a y=_____ 设a>b>1,log(a)b+log(b)a=10/3,则log(a)b-log(b)a= 已知a=log₂3+log₂√3,b=log₂9-log₂√3,c=log₃2,则a,b,c的大小关系是?
