Log 100 1000=x

Log 100 1000=x [( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X log 下面100上面1000 =x x为多少 可以说log a x +log a y=log a log(x)(100)-lgx+1=0 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) solve:log(x)+log(2x)=2 log(X+5)+log(X+2)=1 解方程log(x+1)-log(x-1)=1. x=log a 2 (log(2)(x))^3-4(log(4)(x))^2+log(16)(x)=0 关于log的题如果log(x)+log(x+3)=1那么x等于多少? log(2)(x)log(2)(4x)-3log(2)(x)-12=0 对数的运算问题-log a 1/x=-(log a 1-log a x)=log a x 2log(b)x=log(a)x+log(c)x求证,c^2=(ac)^[log(a)b] log₂log₃log₄ X=log₃log₄log₂ Y=log₄log₂log₃ Z=0X+Y+Z=?为什么是71呀? 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x+y的值
