(1/2)^x=log1/3(x),
log1/4(x+3)-log4(x-1)=log1/4(x+9)?
解下列不等式log1/2(3x-1)>log1/2(x+1)-1
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)
设M={x|log1/2(x²-3x-4)>log1/2(2x+10)},N={x|(x²-10ax
已知x满足不等式log1/2(x^2)≥log1/2(3x-2),求函数f(x)=log2(x/4)*log2(x/2)
已知f(x)=log1/3(3x²-2x-1)求f(x)的定义域
log1/2(9^(x-1)-5)=log1/2(3(x-1)-2)-2
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)
解不等式log1\2( x^2-2x) >-3
log1/2(x²-2x-3)>=1/32,
已知函数y=log1/2[(3-x)(1-x)]
