(log2 x)=(log2 x)^2-log2 x+2 (1) =(log2 x-0.5)^2+7/4 (2) 第一步式子 如何转化成第二步的

log2^(x^log2^x)=? 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) log4(log2^x)=log2(log4^x)求log2^x log2(-x)=x+ |2x-log2^x| 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+1)+log2 x=log6 |[log2(x)]^2-3log2(x)+1| 化简：(log2(x/4))*(log2(x/2)) 解方程log2(x+14)-log2(x+6)=3-log2(x+2)
