求log(x+3)

求log(x+3) 2 log(3x)= log 4 +log(6-x)怎么求...急 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x+y的值 log(2x)+log(3y)-log(2z) 怎么化简?log3(x^2-2x-6)=2 log(3x+6)=1+log(x)求解,求每步详...log(2x)+log(3y)-log(2z) 怎么化简?log3(x^2-2x-6)=2 log(3x+6)=1+log(x)求解, log数学题,求救!高中水平就可以!log(x+8)-log2=log(3x+2)求x. 1.求x的实数范围满足log(4-x)+log(x+3) 已知log(a)x^2>log(a)2x+3,求x的取值范围 求函数y=log小3 x+log小x 3-1的值域rt log(1/2) (x+1)>log(1/4) (3x+4)求对数不等式 log下标（1/3）=2log下标2x,求x. Log 下标X 中标5=3 ,怎么求X 1/[(log(x))^log(x)]求积分 该怎么求 若log(x+3) 一道高一数学题：解方程：log(0.5x)(2)-log(0.5x^3)(X^2)=log(0.5x^3)(4) 求大神详细解!Orz [( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X 设y=1+log a(x+3),求反函数 已知log以3为底(x-1)=log以9为底(x+5),求x的值 （高一）若x满足2(log(1/2)x)^2-14log(4)x+3≤0,求f(x)=[log(2)(x/2)]*{log(√2)[(√x)/2]}的最大值和最小若x满足2(log(1/2)x)^2-14log(4)x+3≤0,求f(x)=[log(2)(x/2)]*{log(√2)[(√x)/2]}的最大值和最小值,并求此时x的值.rt
