log(2)(x+4)=3^x

log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4) (log(2)(x))^3-4(log(4)(x))^2+log(16)(x)=0 log(2)(x)log(2)(4x)-3log(2)(x)-12=0 log(2)(x+4)=3^x 已知log(2){log(3)[log(4)(x)]}=5^0,则x=? 2 log(3x)= log 4 +log(6-x)怎么求...急 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x+y的值 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 解方程3log(x)4+2log(4x)4+3log(16x)4=0 [log(4)(2x)][log(2x)(3y)][log(3y)(z)]=log(8x)[(8x)]^2,则z=? 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 log（x+5）=log（x）+log（2） log（8）+log（x）=log（24） 2log（x）=log(2x)+log(3) 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= 解方程：log√x 2x=4log√x 2x=4 一道高一数学题：解方程：log(0.5x)(2)-log(0.5x^3)(X^2)=log(0.5x^3)(4) 求大神详细解!Orz 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, （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
