2log(x)25-3log(2)5x=1急用,2小时内最好完成

log（x+5）=log（x）+log（2） log（8）+log（x）=log（24） 2log（x）=log(2x)+log(3) 已知log(2){log(3)[log(4)(x)]}=5^0,则x=? log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4) log(X+5)+log(X+2)=1 log(2)(x)log(2)(4x)-3log(2)(x)-12=0 (log(2)(x))^3-4(log(4)(x))^2+log(16)(x)=0 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x+y的值 2 log(3x)= log 4 +log(6-x)怎么求...急 2log(x)(25)-3log(25)(x)=1怎么解X啊.急 log(2)(x+4)=3^x 解方程3log(2)(x)+2log(x)(2)-5=0 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=? [( log(x^2) + log(x^4) )/ log(100 x)] = 4 求X 2log(x)25-3log(2)5x=1急用,2小时内最好完成 solve:log(x)+log(2x)=2 x=log a 2
