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= 【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- 解方程[log(a)(x-1)]-[log(a)(2x-3)]=log(a)(1/3-x),(a＞0,且a≠1). 设y=log(a)((x-3)/(x+3)) (a＞0,a≠1)的定义域为[s,t）,值域为（log(a)((at-a) 设log(a)（x+y)=根号三,log(a)x=1,求log(a)y 设a>b>1,且loga(b)+log(b)a=10/3,求loga(b)-log(b)a 设a=1/log(4)3+1/log(7)3,求证a属于(3,4) 证明：log(A)M=log(b)M/log(b)A (b>0且b≠1）. log(2)3=a,则log(6)4=（ 设a>0,a≠1,x,y满足log以a为底x的对数+3log以x为底a的对数-log以x为底y的对数=3. 已知a^2=m,a^3=n,a＞0且a≠1,求2log a m+log a n 已知y=log以a为底(2-ax)在(0,1)上是增函数,则不等式log以a为底|x+1|＞log以a为底|x-3|的解
