已知常数a>1,变量x,y之间有关系式log(底a)X+3log(底x)a-log(底x)y=3.
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log﹙底a﹚x+3log﹙x﹚a-log﹙x﹚y=3﹙a>1﹚若x=a的t次幂,用a,t,表示y
设log(a)(x+y)=根号三,log(a)x=1,求log(a)y
已知log(2)[log(3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x
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
y=log(1/a)底x与y=loga底x关于?轴对称
1.求函数y=log以a为底(a^x-1)的对数(a>0且a≠1)的定义域2.求函数y=log以(x-1)为底(3-x)
设a>1,若对于x∈[a,2a],都有y∈[a,a^2]满足方程log以a为底的x+log以a为底的y=3,则a的取值范
函数y=log以a为底x,当log以a为底(x^2-x+1)小于等于log以a为底3/4成立时,a的取值范围.
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)
已知函数y=log以a为底(a-a^x)(a>1)求定义域与值域
1、以知x^2+y^2=1,x>0,y>0,且log以a为底的(x+1)=m,log以a为底的1/1-x=n,则log以
