log(2){x^2}=x,求x的值除了2还有一个是？

log(2){x^2}=x,求x的值除了2还有一个是？ 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 b x=1,log c x=4,求log abc x 的值 [( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X 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 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 f(x)=|log(a)(x)-1|+|2log(a)(x)|,求使f(x)＜2的x范围, 已知:2^x=1/21:求x的取值范围(2)求函数(x)=log(x/2)×log(根号x/2)的最大值和最小值 2x = log(3)(8x^2 + 7) 求x的值, log(x+3)(x2+3x)=2,求实数x的值 已知x属于[根号2,8],求f(x)=[log(2)(x/2)乘log(2)(x/4)]最大值,最小值与相应的x的值. 已知log a (xy)==√2,log a (ay)=2 求log a x的值 lg(7*2^x+8)>=log(√10) 2^x,求函数f(x)=log(1/2)x*log(1/2)x/4的最小值 2 log(3x)= log 4 +log(6-x)怎么求...急 log(8)(2)^x加log(7)(1/根号3次49)=1,求x的值 求函数f(x)=-(log(0.5)x)²-log(0.25)x+5在[2,4]范围内的最值,并求出相应的x的值
