log1/2(4^x+2^(x+1))>0
log1/2(4^x+2^(x+1))>0
解不等式log1/2(x平方-x-2)>log1/2(x-1)-1
解不等式:log1/3(x²-3x-4)>log1/3(2x+10)
解下列不等式log1/2(3x-1)>log1/2(x+1)-1
已知x满足不等式:2(log1/2 x)²+7log1/2 x +3≤0,则函数f(x)=(log2 x/4)
log4(x+3)+log1/4(x-3)=log1/4(x-1)+log4(2x+1),说明:
若2(log1/2x)2+7log1/2x+3小于等于0,求Y=log1/2(x/2).log2(x/4)的最大值与最小
已知x满足不等式2(log1/2^x)^2+(7log1/2^x)+3≤0,
