log(1/2) |x-1|>0

log(1/2) |x-1|>0 log(X+5)+log(X+2)=1 log底数7[log底数3（log底数2X）]=0,那么x^1/2的值是 log根号2（X-1) log(9)x+log(x^2)3=1的解为?原方程可可化为log(3 ²)x+log(x)²3=1 ,∴1/2*log(3)X+1/2*log(x)3=1,∴[log(3)x]²-2log(x)3+1=0,即[log(3)x-1]²=0请问这里的[log(3)x]²-2log(x)3+1=0是怎么推出来的,刚学基础不好, log(a-1) (2x-1)-log(a-1)(x-1)>0 解[log(x-1)]²+2log(x-1)-3=0 已知log(8)[log(3)X]=0,那么X^(-1/2)= log(1/8)X 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, 解方程[log(a)(x-1)]-[log(a)(2x-3)]=log(a)(1/3-x),(a＞0,且a≠1). 1/log（2）x+1/log（3）x+1/log（4）x=1,x=? （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0＜a＜1,x=log a 根号2＋log a 根号3y=1/2 log a 5z=log a 根号21 －log a 根号3比较x y z 的大小关系x=log a （根号2）＋log a （根号3）y=1/2 （log a 5）z=log a （根号21） －log a （根号3） 试解关于x的不等式log(2)x+4log(3)x+12log(8)x+n·2^(n-1)·log(2^n)x 对数计算1.{log(4)（3）+ log(8) (3)} X {log(3)(2)+log(9)(2)}2.{log(2)(3)} X {log(3)(4)+log(9)(2)}3.(lg2)^+1g2X 1g5 +1g50 若f(x)=log a (1-x),g(x)=log a (1+x) 0 log 3 (4+x+4y)^2=0 联立 log 2 (x+1)^2=1+3log 2 y^2 求
