1+log2底x=2log2底(x-a)恰有一个 实数解,a的取值范围如题

[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 log2 (x + 3) + log2(x + 2) = 1log2 (x + 3) + log2(x + 2) = 1 log2底x=2^x log2 (x+1)+log2 x=log6 |[log2(x)]^2-3log2(x)+1| 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. 解方程log2(2-x)=log2(x-1)+1 解2log2^(x-5)=log2^(x-1)+1 求解log2(3x)=log2(2x+1) log2^(x^log2^x)=? log2为底(x+1) log2(x)=-1 log2(2X-1) 若1/2≤log2底x≤3,求函数y=（log2底x－1）.（log2底x－2）的值域 log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5) log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5) 画出y=log2底|x|+1和y=log2底|x+1|的图像 log2 4+log2 (x+2)怎么算?log2 4+log2 (x+2)=log2 (4x+8)
