log2(x+1)分之(x-1)log2(x+1)分之(x-1)log2(x+1)分之(x-1)0(x-1)log2(x+1)0。得-10,x+1
log2 (x+1)分之(x-1)
log2 (x+1)分之(x-1)
log2 (x+1)分之(x-1)
0
(x-1)log2(x+1)<0,第一种情况x-1<0,x+1>0。得-1
log2 (x+1)分之(x-1)
|[log2(x)]^2-3log2(x)+1|
log2(x+1)>log2(3-x)
log2 (x+1)+log2 x=log6
解不等式 log2(X平方+2X)>log2分之一(5-2X分之1)
不等式log2 (x+1)
log2(2X-1)
log2(x²+1)
log2(x-1)
log2(x)=-1
log2(x+1)
log2(x-1)
log2(x-1)
log2 (x + 3) + log2(x + 2) = 1log2 (x + 3) + log2(x + 2) = 1
.log2^(x+1/x+6)
y= log2 x分之1 的定义域,
函数y=log2^(log2分之1 ^x)的定义域是?
f(x)=log2分之1(-x平方+2x);f(x)的值域和区间
