用log求x的值 3^x=2^x-13^x=2^x-110^-x=5^2x27=3^5x * 9^(x^2)e^x+e^-x=5请写出详细的解答过程.

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(a)x^2>log(a)2x+3,求x的取值范围 （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 已知log a x=2,log b x=1,log c x=4,求log abc x 的值 log(x+3)(x2+3x)=2,求实数x的值 2x = log(3)(8x^2 + 7) 求x的值, 2 log(3x)= log 4 +log(6-x)怎么求...急 log(0.1)log(0.2)log(0.5)(1/根号5次2）=x,求x的值 log(x-1) (x^2-8x+7)=1,求x的值 [( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X log(8)(2)^x加log(7)(1/根号3次49)=1,求x的值 已知log(a)x=2,log(b)x=3,log(c)x=6,求log(abc)x的值（括号里的为底数,外面的是真数）急已知log(a)x=2,log(b)x=3,log(c)x=6,求log(abc)x的值（括号里的为底数,外面的是真数）急~ 求log(x+3) 若b>1,x>0,且(2x)^log(b)2-(3x)^log(b)3=0,求x的值.明天就要考了. 已知log以3为底(x-1)=log以9为底(x+5),求x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, 已知log∨7∧[log∨3∧（log∨2∧x）]=0 求X∧1/2的值 f(x)=|log(a)(x)-1|+|2log(a)(x)|,求使f(x)＜2的x范围,
