log2(x²+1)
已知函数f(x)=log2(x+1)/(x-1)+log2(x-1)+log2(p-x)求f(x)的值域f(x)=log2(x+1)/(x-1)+log2(x-1)+log2(p-x) 的定义域算出来是(1,P)=log2【 【(x+1)/(x-1) 】·(x-1)·(P—x)】=log2【(x+1)·(P—x)】=log2【-x²
解方程:log2(x²-3)=2log4(6x-10)-1
f(x)=log2(x²+1)的图像怎么画
|[log2(x)]^2-3log2(x)+1|
log2(x+1)>log2(3-x)
log2 (x+1)+log2 x=log6
不等式log2 (x+1)
log2(2X-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)
已知x满足不等式2(log 1/2x)² +7log1/2x+3≤0,求函数f(x)=(log2四分之x)*(log2二分之x)的最大值和最小值
