于是f(x)=9[log(4,x)]^2-[log(2,x)]^2=9[1/2*log(2,x)]^2-[log(2,x

4^log(4)[x^2]+3^log(9)[6x]=log(2)[16] log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4) [( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X log(X+5)+log(X+2)=1 f(x)=2log(5)x 对数计算1.{log(4)（3）+ log(8) (3)} X {log(3)(2)+log(9)(2)}2.{log( f(x)=log^2(x+1)/(x-1)+log^2(x-1)+log^2(p-x)的值域（负无穷,log^(p+1) solve:log(x)+log(2x)=2 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x 2 log(3x)= log 4 +log(6-x)怎么求...急 x=log a 2 1/log（2）x+1/log（3）x+1/log（4）x=1,x=?
