log2 x+log2 (x-3/8)+4=0怎么解是log2（下标）xlog2（下标）(x-3/8)

log2(x+1)+log2(x+8)=3的解集是? |[log2(x)]^2-3log2(x)+1| log2(x+1)>log2(3-x) log2 (x + 3) + log2(x + 2) = 1log2 (x + 3) + log2(x + 2) = 1 log2^(x^log2^x)=? log2 4+log2 (x+2)怎么算?log2 4+log2 (x+2)=log2 (4x+8) f(x)=log2(x/8)*log2(2/x) 解方程：log2(x)+log2(x-8)=7 解不等式log2(4x+8)>log2(2x+1) 求函数Log2(8x).Log2(4x)其中2 求函数Log2(8x).Log2(4x)其中2 求解log2(3x)=log2(2x+1) 不等式log2(2x+3)>log2(x+1)的解集是 不等式log2(2x-3) log2为底x+3 log2(x^2-3)>0 log2(3),log2(3^x-1),log2（3^x+37/3）成等差数列,求x 解方程：log2(x+4)+log2(x-1)=1+log2(x+8)
