谁能帮忙解一下：log2(x – 2 ) + 2 = log25log2(x – 2 ) + 2 = log25谢谢~

谁能帮忙解一下：log2(x – 2 ) + 2 = log25log2(x – 2 ) + 2 = log25谢谢~ 谁能帮我解一下：log2(x + 1) = 4 - log2(x + 1)log2(x + 1) = 4 - log2(x + 1) log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5) log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5) 已知函数f（x）=log2（x+1/x-1）+log2（x-1）+log2（p-x） 求函数f（x）的值域,谁能给我讲解一下, log2(x2-x-2)>log2(2x-2)解不等式 解不等式2log2 (x-4)< log2 (x-2) 解方程log2(2-x)=log2(x-1)+1 解不等式log2(4x+8)>log2(2x+1) 解2log2^(x-5)=log2^(x-1)+1 解方程log2(x+14)-log2(x+6)=3-log2(x+2) !谁能帮忙分析一下 谁能帮忙翻译一下! 解不等式：log2(x^2-x-2) 解不等式log2(4x-x^2) |2x-log2^x| |[log2(x)]^2-3log2(x)+1| 化简：(log2(x/4))*(log2(x/2))
