已知log(2)X,log(2)|X|,log(2)(-X),-log(2)X的图像怎么画?不过(3) 就是将log(2)X的x换成-x,就是关于轴对称。关于哪个轴对称啊?

已知log(2)[log(3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x+y的值
已知log(2){log(3)[log(4)(x)]}=5^0,则x=?
2log(m)y-log(m)x-log(m)z
已知log a x=2,log b x=1,log c x=4,求log abc x 的值
已知log(a)x=1,log(b)x=2,log(c)x=4,则log(abc)x=?
已知log(a)x^2>log(a)2x+3,求x的取值范围
log(x+5)=log(x)+log(2) log(8)+log(x)=log(24) 2log(x)=log(2x)+log(3)
log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4)
已知log(8)[log(3)X]=0,那么X^(-1/2)=
[( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X
solve:log(x)+log(2x)=2
log(X+5)+log(X+2)=1
log₂X 怎样变为log₂(2X)
已知log(2)X,log(2)|X|,log(2)(-X),-log(2)X的图像怎么画?不过(3) 就是将log(2)X的x换成-x,就是关于轴对称。关于哪个轴对称啊?
已知log a (xy)==√2,log a (ay)=2 求log a x的值
log底2(x-2)
log根号2(X-1)
x=log a 2
