若-3≤log(1/2)x≤-1/2,则函数y=(log(2)x－1)(log(2)x－2)的值域为?

若-3≤log(1/2)x≤-1/2,则函数y=(log(2)x－1)(log(2)x－2)的值域为? （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 2log∨6x=1-log∨6 3,则x的值是什么 1、若lg2=a,lg3=b,则lg√15=?（用a、b表达）2、若log(15)(5)=m,则log(15)(3)=(用m表示)3、log(2)(3)*log(3)(4)*log(4)(5)*log(5)(6)*log(6)(7)*log(7)(8）=?4、设log(3)(2)=log(2)(3^x),x=?这个对数函数我学的很不好,所以希望过 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, 若log底数2[log底数3(log底数4)]若log底数2[log底数3(log底数4（x）)]=log底数3[log底数4(log底数2(y))]=log底数4[log底数2(log底数3z)]=0,则x+y+z= 1/log（2）x+1/log（3）x+1/log（4）x=1,x=? 若log(2x+3)^(1-4x) 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 无穷等比数列log(8)x,log(8^2)x,log(8^3)x……各项之和为1/2,则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 log(X+5)+log(X+2)=1 log 9 X/Y=1/2(log 3 X - log 3 Y) log 9 X/Y=1/4 3log 3 X =2log 3 Y find X and Y 2log^(x^2) = 3{2^(1+log x)} + 16 2log^(x^2) = 3{2^(1+log x)} + 16 log根号2（X-1) 已知log(a)x=1,log(b)x=2,log(c)x=4,则log(abc)x=? 解不等式log底数是1/2(2x²-3x-7)≤log底数是1/2(x²+x-2)过程哦 log(1/2)^(x^2+2x-3)>log(2)^[1/(3x-1)]
