f(x)=log2为底x减去2/log2为底x,(0要有过程f(2^a乘n）=2n

f(x)=log2为底x减去2/log2为底x,(0要有过程f(2^a乘n）=2n [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 f(x)=log2(x/8)*log2(2/x) 已知f(x)是奇函数,且f(2-x)=f(x),当x∈[2,3]时,f(x)=log2(x-1),则当x∈[1,2]时,f(x)=____.A.-log2(4-x) B.log2(4-x) C.-log2(3-x) D.log2(3-x)注：对数都是以2为底的. log2^(x^log2^x)=? 为了得到函数f(x)=log2( x)的图像,只需将函数f(x)=log2(x/8)的图像如何平移f(x)=log2(x)是指log以2为底,x的对数 函数F(X)满足F[1/（X+|X|)]=LOG2√（X|X|）,则F(X)的解析式是 LOG2是以2为底的对数LOG2是以2为底的对数 f(x)=log2为底真数为(3^x+1/3^x-2)的值域 已知函数f(x0=log2为底x+1/x-1+log2为底（x-1)+log2为底（p-x）,（1）求f(x)定义域。（2).求最值 log2 (x + 3) + log2(x + 2) = 1log2 (x + 3) + log2(x + 2) = 1 已知函数f(x)=log2(2-x)+log2(2+x)求f(x)的定义域 函数f(x)=(log2 x/4)(log2 x/2)的最小值为怎么弄出最小的来 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 f(x)=log2^x,那么log2^x=2x么 f(x)=(log2 X/4)*(log2 X/2),x∈[1/2,4]的值域 F(X)=|X|+|X-2| 求F(log2 3) log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5) log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5)
