f(xy)=f(x)+f(y)且f(8)=3则f(2)=
f(xy)=f(x)+f(y)且f(8)=3则f(2)=
f(xy)=f(x)+f(y)且f(8)=3则f(2)=
f(4)=f(2)+f(2)=2f(2)
f(8)=f(4)+f(2)
3=2f(2)+f(2)
3=3f(2)
f(2)=1
f(xy)=f(x)+f(y)且f(8)=3则f(2)=
f(xy)=f(x)+f(y)且f(8)=3 求f(根号2)
若f(xy)=f(x)+f(y)且f(4)=1求f(1/16)若f(x+y)=f(xy) 求f(1)
f(xy)=f(x)+f(y),证明f(x/y)=f(x)-f(y)
导数:f(x+y)=f(x)f(y),且f'(o)=1,求f'(x)f(x+y)=f(x)f(y),且f'(o)=1,求f'(x)f(x+y)=f(x)+f(y)+2xy,且f'(o)存在,求f'(x) f(1+x)=af(x),且f'(0)=b,求f'(1)
函数f(x)的定义域为R+,且f(xy)=f(x)+f(y),且f(8)=3,则f(32)=
函数y=f(x)的定义域为R,且f(xy)=f(x)+f(y),f(8)=3,则f(根号2)=
y=f(x)的定义域(0,+∞),且f(xy)=f(x)+f(y),f(8)=3,则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
设函数y=f(x)的定义域为R,且f(xy)=f(x)+f(y),f(8)=3,则f(根号2)等于
已知f(x)的定义域为{x|x>0}且f(xy)=f(x)+f(y),若f(9)=8,求f(3)的值
{已知f(x)的定义域为{x|x>o},且f(xy)=f(x)+f(y),若f(9)=8,求f(根号3)
急:已知f(x)的定义域为{X|X>0},且f(xy)=f(x)+f(y),若f(9)=8,求f(3).
f(xy)=f(x)+f(y),f(8)=3,则f(根2)等于
f(xy)=f(x)+f(y),f(8)=3,求f(√2),
函数f(x)定义域R且为增函数,f(xy)=f(x)+f(y)证明f(x/y)=f(x)-f(y)
f(x)是定义域在正实数的递增函数,且f(xy)=f(x)+f(y),求证:f(x/y)=f(x)-f(y)
1.对任意的正数函数f(x)满足f(xy)=f(x)+f(y),且f(8)=3,则f(2)=?
