若log(2x+3)^(1-4x)

（高一）若x满足2(log(1/2)x)^2-14log(4)x+3≤0,求f(x)=[log(2)(x/2)]*{lo 1/log（2）x+1/log（3）x+1/log（4）x=1,x=? log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4) 4^log(4)[x^2]+3^log(9)[6x]=log(2)[16] 2 log(3x)= log 4 +log(6-x)怎么求...急 对数计算1.{log(4)（3）+ log(8) (3)} X {log(3)(2)+log(9)(2)}2.{log( 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x 解不等式:log½(x²-1)>log½(2x²-x-3) [( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X 若不等式log（3-2x） y=log(4)(1-2x+x^2) =log(2)[(1-x)^2] /log(2)(4) =2[log(2)|1-x log(2x)+log(3y)-log(2z) 怎么化简? log3(x^2-2x-6)=2 log(3x+6)=1+l
