解不等式:log(2底)(x^2-1)≤1解不等式:log(2底)(x^2-1)≤1解不等式:log(2底)(x^2-1)≤1log2(x^2-1)01-根号3log(2底)(x^2-1)≤1=log

解不等式:log(2底)(x^2-1)≤1
解不等式:log(2底)(x^2-1)≤1

解不等式:log(2底)(x^2-1)≤1
log2(x^2-1)<=1=log2(2)
01-根号3<=x<=-1或1<=x<=根号3

log(2底)(x^2-1)≤1=log22
x^2-1>0
x>1 x<-1
x^2-1≤2
-√3≤x≤√3
∴-√3≤x<-1 or 1

log(2)(x^2-1)<=1<=log(2)(2),
x^2-1<=2
x^2<=3
-sqr(3)<=x<=sqr(3)
