设函数y=f(x)的定义域为R+,且f(xy)=f(x)=f(y),f(8)=3,则f(更号2)=
1、设函数f(x)的定义域为R+,f(xy)=f(x)+f(y)且f(8)=3,求f(根号2)
设函数y=f(x)的定义域为(0,+∝)且f(xy)=f(x)+f(y),f(8)=3则f(根号2)等于
函数f(x)的定义域为R+,且f(xy)=f(x)+f(y),且f(8)=3,则f(32)=
设函数f(x)的定义域为R,且x,y∈R,恒有f(xy)=f(x)+f(y),若f(8)=3,则f(根号2)=
设函数f(x)的定义域为R,且对x,y∈R,恒有f(xy)=f(x)+f(y),若f(8)=3,则f(2)= ___ .
设函数f(x)的定义域为正实数,f(xy)=f(x)+f(y)且f(8)=3,求f根号2
设函数f(x)定义域为R,且满足f(xy)=f(x)+f(y),则f(1/x)+f(x)=______
设函数y=f(x)的定义域为R+,且f(xy)=f(x)+f(y),f(8)=3,则f(2)是多少?
设函数f(x)定义域为R,且满足f(xy)=f(x)+f(y),求f(0)与f(1)的值
