log2(x+1/(x-1)+5)(x>1)的最小值是多少?
log2(x+1/(x-1)+5)(x>1)的最小值是多少?
log2(x+1/(x-1)+5)(x>1)的最小值是多少?
令y=x+1/(x-1)+5
=(x-1)+1/(x-1)+6
因为x>1,所以x-1>0
所以,y>=2根号[(x-1)/(x-1)]+6=8
所以log2(y)>=log2(8)=3
|[log2(x)]^2-3log2(x)+1|
log2(x+1)>log2(3-x)
log2 (x+1)+log2 x=log6
解2log2^(x-5)=log2^(x-1)+1
解不等式:|log2(x-1)|+log2(5-x)
.log2^(x+1/x+6)
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 1]+[log2 2]+[log2 3]+[log2 4]+[log2 5]+...+[log2 1024]=?[x]表示不超过x的最大整数2为底 答案是8204
解不等式 log2(X平方+2X)>log2分之一(5-2X分之1)
高一不等式,要过程(1) log2(x加5)>log2(3-x) (2) 2^x
