已知x满足log2(x+4)-log2(x-3)＞1求x的取值范围

已知x满足log2(x+4)-log2(x-3)＞1求x的取值范围 化简：(log2(x/4))*(log2(x/2)) 已知x满足不等式2[log2(x)]^2-7[log2(x)]+3≤0,求函数f（x）=[log2(x/2)]*[log2(x/4)]的最大最小值. 1.已知正实数x满足不等式log2(x+6) 已知正实数x满足不等式log2(x+6) 已知满足不等式2log2(x)-7log2(x)+3≤0,求函数f（x）=[log2﹙x/2﹚][log2﹙x/4﹚]的最值. log2(4^x+4) 已知x满足不等式log1/2（x）≥log1/2（2-x）,求函数f(x)=[log2(x/4)]*[log2(x/2)]的最小值 log2^(x^log2^x)=? 已知x满足不等式?log1/2 x +3≤0求函数f(x)=(log2 x/4)(log2 x/2)的最值 已知x满足不等式2(log2x)^2-7log2x+3小于等于0求函数F(X)=LOG2(X/2)*LOG2(X/4)的最大值和最小值 已知函数f(x)=log2^ ( x/4 ) ×log2^ (2x) (1)解不等式f(x)>0;(2)当x∈【1,4】时,求f(x)的值域f（x）=log2（2x）×log2（x／4）＝[（log2 2）+(log2 x)] ×[(log2 x) -(log2 4)]=[1+(log2 x)] ×[(log2 x) -2]=(log2 x)² - (log2 x) -2 log2 4+log2 (x+2)怎么算?log2 4+log2 (x+2)=log2 (4x+8) 已知log2 x²＞log2 （3x+4）,求x的取值范围 已知函数y=(log2 x/8)(log2 x/4) (2= 已知函数y=(log2 x/8)(log2 x/4) (2= 解不等式log2(4x+8)>log2(2x+1) 解不等式2log2 (x-4)< log2 (x-2)
