一、已知f（x）=log底下2（x^2+2x+5),g(x)=log底下1/2（x^2-3x+2)

一、已知f（x）=log底下2（x^2+2x+5),g(x)=log底下1/2（x^2-3x+2) f(x)=2log(5)x （高一）若x满足2(log(1/2)x)^2-14log(4)x+3≤0,求f(x)=[log(2)(x/2)]*{lo log(X+5)+log(X+2)=1 log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4) 已知函数F(X)=LOG(X+根号1+X^2),判断F(X)的奇偶性 1/log（2）x+1/log（3）x+1/log（4）x=1,x=? f(x)=|log(a)(x)-1|+|2log(a)(x)|,求使f(x)＜2的x范围, 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x 已知函数f（x）=(a−2)x−1，x≤1log f(x)=log^2(x+1)/(x-1)+log^2(x-1)+log^2(p-x)的值域（负无穷,log^(p+1) 设x大于0且x不等于1,f(x)=1加log下面一个小x大3,g(x)=2log小x大2,试比较f(x)与g(x)的大小
