log2(2x)*log2(x)=2x=?log2(2x)*log2(x)=2x=?log2(2x)*log2(x)=2x=?[log2(2)+log2(x)]*log2(x)=2///导入公式log
log2(2x)*log2(x)=2 x=?
log2(2x)*log2(x)=2 x=?
log2(2x)*log2(x)=2 x=?
[log2(2)+log2(x)]*log2(x)=2 ///导入公式loga(b*c)=loga(b)+loga(c)
[1+log2(x)]*log2(x)=2
令log2(x)=t,则
(1+t)*t=2
t^2+t-2=0
t=1或t=-2
即log2(x)=1 x=2
或log2(x)=-2,x=2^(-2)=1/4
log2 (x + 3) + log2(x + 2) = 1log2 (x + 3) + log2(x + 2) = 1
|2x-log2^x|
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)
|[log2(x)]^2-3log2(x)+1|
化简：(log2(x/4))*(log2(x/2))
