[(log(x^2)+log(x^4))/log(100x)]=4求X[(log(x^2)+log(x^4))/log(100x)]=4求X[(log(x^2)+log(x^4))/log(100x)
[( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X
[( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X
[( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X
没有底数吗?
还是是lg
[( lg(x^2) + lg(x^4) )/ lg(100 x)]
=(2lgx+4logx)/lg(100x)
=6lgx/(2+lgx)=4
6lgx=8+4lgx
所以.lgx=4
x=10000
2log(m)y-log(m)x-log(m)z
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)
[( 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）
log底2(x-2)
log根号2（X-1)
x=log a 2
log(2)(x)log(2)(4x)-3log(2)(x)-12=0
简化2log (x + 4) – log(2x + 8) + log(x - 2)谢谢~
(log(2)(x))^3-4(log(4)(x))^2+log(16)(x)=0
2log(b)x=log(a)x+log(c)x求证,c^2=(ac)^[log(a)b]
已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x+y的值
2 log(3x)= log 4 +log(6-x)怎么求...急
已知log(2){log(3)[log(4)(x)]}=5^0,则x=?
可以说log a x +log a y=log a
