log2(x+14)(x+2)=log2 8+log2(x+6) 2都在下面的
log2^(x^log2^x)=?
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
解方程log2(x+14)-log2(x+6)=3-log2(x+2)
log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2[log2(32)-log2(3÷4)+log2log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2【log2(32)-log2(3÷4)+log2(6)】=?lgx+lg(x+15)=2 ..X
log2(2^x-1)log2(2^(x+2)-4=3log2(2^x-1)log2(2^(x+2)-4)=3
log2 (x + 3) + log2(x + 2) = 1log2 (x + 3) + log2(x + 2) = 1
解关于x的方程:log2(x+14)-log0.5(x+2)=3+log2(x+6)
log2(x+1)+log2x=log2(6)解方程
解方程log2(2x^2-x)=log2(x+1)
log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5)
log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5)
解方程log2(2x+1)=log2(x^-2)
设f(log2 X)=2^x,则f(2log2 3)=
求函数y=log2(x)log2(2x)的值域
y=log2^[1/(x+1)]+log2^(x^2-1)的反函数(过程、、)
log2 4+log2 (x+2)怎么算?log2 4+log2 (x+2)=log2 (4x+8)
log2(2x)*log2(x)=2 x=?
