logx^2=3求xlogx^2=3求xlogx^2=3求xlogx^2=3由对数定义x^3=2x=2^(1/3)
logx^2=3求x
logx^2=3求x
logx^2=3求x
logx^2=3
由对数定义
x^3=2
x=2^(1/3)
已知logx(a)=2 logx(b)=3 logx(c)=6 求logabc(x)
logx+logx^2+log^3+.logx^10=110,求X的值帮帮忙哦
logx^2=3求x
logx(3+2倍根号2)= -2 求X
logx(3-2√2)=2,求x
logx(8)= 3/2,求x
logX(1/8)=3/2,求x
logx底8=-2求x
logX=1.673006求X logX=1.794261求X
函数f(x)=1-logx(2)+logx^2(9)-logx^3(64),那么是f(x)
log2(x)=-2/3 logx(3+2根号2) 求x.(1) log2(x)=-2/3 (2) logx(3+2根号2)=-2 。求x
求y=log2 X+logx (2X)的值域
求y=log2 x+logx (2x)的值域
logx(x+1)+logx(x+2)=logx6+1
log2X=- 2/3 求X logx(3+2根号2)=-2求X
已知函数f(x^2-3)=logx^2/x^2-6,求f(x)定义域
求函数y=logx(2-|x|)的定义域.
求函数y=logx^2-1底(x^2+2x-3)的定义域
