请问如何化简算式：log根号x+1/log(100x)

请问如何化简算式：log根号x+1/log(100x) log(2x)+log(3y)-log(2z) 怎么化简? log3(x^2-2x-6)=2 log(3x+6)=1+l 请问如何证明log（2）（x）+x < 4^(x-1),(x>=2) f(x)=log2(x/2)乘log根号2(根号x/2)怎么化简 设log(a)（x+y)=根号三,log(a)x=1,求log(a)y log(0.1)log(0.2)log(0.5)(1/根号5次2）=x,求x的值 log根号2^（x-5）log2^(x-1) log根号2^(x-5)-log2^(x-1) 数学对数函数运算请问log 0.5 {(-x)+√[(-x)^2+1]}+log 0.5 [x+√(x^2+1)]如何运 若|log(sinx)cosx|+|log(cosx)根号tanx|=1,求锐角x.要具体过程. log(x)(100)-lgx+1=0 函数y=根号log(1/2)x的定义域
