log(x)4/5log(x)4/5log(x)4/5log(x)4/5log(x)4/5当x>1，意味着函数单调增，于是x>4/5,于是合起来，x>1。于是解为01主要看单调性喔ln0.8/lnx(
log(x)4/5
log(x)4/5
log(x)4/5
log(x)4/5
log(x)4/5<1=lg(x)x.当0
于是解为0
主要看单调性喔
ln0.8/lnx<1
(1)若lnx>0，则ln0.8
(2)若lnx<0，则ln0.8>lnx
所以0
log(x)4/5
已知log(2){log(3)[log(4)(x)]}=5^0,则x=?
log的底数5乘以(log的底数4(log的底数3(x)))=0
化简:1/log(3)x 1/log(4)x 1/log(5)x=……(答案是1/log(60)x
于是f(x)=9[log(4,x)]^2-[log(2,x)]^2=9[1/2*log(2,x)]^2-[log(2,x)]^2=5/4*[log(2,x)]^2 怎么得的?
设方程式为log(2)(x)-5log(x)(2)=4,其解集合为?
log（x+5）=log（x）+log（2） log（8）+log（x）=log（24） 2log（x）=log(2x)+log(3)
(log(2)125+log(2)25+log(8)5)*(log(125)2+log(25)4+log(5)8)
[( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X
log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4)
方程log（3^x+4^x）=log（5^x-3^x）的解集为
log(X+5)+log(X+2)=1
(log(2)(x))^3-4(log(4)(x))^2+log(16)(x)=0
log(2)(x)log(2)(4x)-3log(2)(x)-12=0
简化2log (x + 4) – log(2x + 8) + log(x - 2)谢谢~
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)x=5,log(3)y=-2,求log(6)[3x/4y]...（括弧者为底数）
2 log(3x)= log 4 +log(6-x)怎么求...急
