log2^x=-2/3 求x 麻烦写出解答过程结果为³√2/2 log2(x)=-2/3,求x 解方程log2(x+14)-log2(x+6)=3-log2(x+2) log2 (x + 3) + log2(x + 2) = 1log2 (x + 3) + log2(x + 2) = 1 log2[(x-14)(x-2)]=3+log2(6-x).求x?. log4(log2^x)=log2(log4^x)求log2^x F(X)=|X|+|X-2| 求F(log2 3) 函数f(x)=log2(1+x)+log2(3-x (1)求函数f(x)的定义域 (2)求函数f(函数f(x)=log2(1+x)+log2(3-x(1)求函数f(x)的定义域(2)求函数f(x)的值域(3)写出函数f(x)的单调区间 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 log1/3 3 =2log2 x 求x 求y=log2(3-2x-x^2)值域 已知log3(2) =log2(3)^x .求x f[log2(x)]=2^x,求f(3) 求y=(log2 x-2)(1/2 log2 x-3)(2 求y=log2^x(log2^4x^2)+3的值域 解方程log2(2-x)=log2(x-1)+1 解2log2^(x-5)=log2^(x-1)+1 求解log2(3x)=log2(2x+1)
