2 log(3x)= log 4 +log(6-x)怎么求...急
log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4)
1/log(2)x+1/log(3)x+1/log(4)x=1,x=?
4^log(4)[x^2]+3^log(9)[6x]=log(2)[16]
已知log(2)[log(3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x
化简:1/log(3)x 1/log(4)x 1/log(5)x=……(答案是1/log(60)x
[( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X
