log2(x^2-2)=log2(10x+8)-1 我算不出来.

log2 (x + 3) + log2(x + 2) = 1log2 (x + 3) + log2(x + 2) = 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) log2 4+log2 (x+2)怎么算?log2 4+log2 (x+2)=log2 (4x+8) log2(2x)*log2(x)=2 x=? f(x)=log2(x/8)*log2(2/x) |2x-log2^x| |[log2(x)]^2-3log2(x)+1| 化简：(log2(x/4))*(log2(x/2)) 求导 y=log2(x^2)-log2(x) 求解log2(3x)=log2(2x+1) 解方程log2(2-x)=log2(x-1)+1 解2log2^(x-5)=log2^(x-1)+1 log2^(x^log2^x)=? 解方程log2(x+14)-log2(x+6)=3-log2(x+2) log2(2X-1) log2(x^2)图像 log2(x-2)
