log2(4^x+4)=x+log2(2^x+1-3)log2(4^x+4)=x+log2[2^(x+1)-3]log2(4^x+4)=x+log2(2^x+1-3)log2(4^x+4)=x+log
log2(4^x+4)=x+log2(2^x+1-3)log2(4^x+4)=x+log2[2^(x+1)-3]
log2(4^x+4)=x+log2(2^x+1-3)
log2(4^x+4)=x+log2[2^(x+1)-3]
log2(4^x+4)=x+log2(2^x+1-3)log2(4^x+4)=x+log2[2^(x+1)-3]
log2(4^x+4)=log2(2^x)+log2[2^(x+1)-3]
令2^x=a
4^x=a²
2^(x+1)=2a
log2(a²+4)=log2(a)+log2(2a-3)
log2(a²+4)=log2(2a²-3a)
a²+4=2a²-3a
a²-3a-4=0
a=4,a=-1
a=2^x>0
所以2^x=4
x=2
log2 4+log2 (x+2)怎么算?log2 4+log2 (x+2)=log2 (4x+8)
化简:(log2(x/4))*(log2(x/2))

已知函数f(x)=log2^ ( x/4 ) ×log2^ (2x) (1)解不等式f(x)>0;(2)当x∈【1,4】时,求f(x)的值域f(x)=log2(2x)×log2(x/4)=[(log2 2)+(log2 x)] ×[(log2 x) -(log2 4)]=[1+(log2 x)] ×[(log2 x) -2]=(log2 x)² - (log2 x) -2
不等式log2(2x-4)
谁能帮我解一下:log2(x + 1) = 4 - log2(x + 1)log2(x + 1) = 4 - log2(x + 1)
解方程:log2(x+4)+log2(x-1)=1+log2(x+8)
