2x = log(3)(8x^2 + 7) 求x的值,

log（x+5）=log（x）+log（2） log（8）+log（x）=log（24） 2log（x）=log(2x)+log(3) log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4) log数学题,求救!高中水平就可以!log(x+8)-log2=log(3x+2)求x. log(2)(x)log(2)(4x)-3log(2)(x)-12=0 (log(2)(x))^3-4(log(4)(x))^2+log(16)(x)=0 log(x.8)-3log(8,x)=2 要X [log(4)(2x)][log(2x)(3y)][log(3y)(z)]=log(8x)[(8x)]^2,则z=? log(2)(x+4)=3^x log底数7[log底数3（log底数2X）]=0,那么x^1/2的值是 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(8)[log(3)X]=0,那么X^(-1/2)= lg(7*2^x+8)>=log(√10) 2^x,求函数f(x)=log(1/2)x*log(1/2)x/4的最小值 已知log（2）[log（3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x+y的值 log(8)(2)^x加log(7)(1/根号3次49)=1,求x的值 1/log（2）x+1/log（3）x+1/log（4）x=1,x=? 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, 2x = log(3)(8x^2 + 7) 求x的值,
