(1/2)^-1/2=log1/2 x,x等于多少?

log1/2 x≥1 x等于多少 y=log1/2(x+1) 求函数f(x)=(log1\2x)^2-1\2log1\2x+5 集合A={x/log1/2的X次方大于等于1/2}求CrA log1/2(9^(x-1)-5)=log1/2(3(x-1)-2)-2 log1/2(x²-2x-3)>=1/32, 已知函数y=log1/2[(3-x)(1-x)] f(x)=根号log1/2 (x-1)的定义域 log4(x+3)+log1/4(x-3)=log1/4(x-1)+log4(2x+1),说明： 解不等式log1/3(2x-1) 1.解不等式log1/2(x^2-x-2)>log1/2(x-1)-1 解不等式：1+log1/2(x^2-x-2)>log1/2(x-1)
