化简:1/log3(x)+1/log4(x)+1/log5(x)=化简:1/log3(x)+1/log4(x)+1/log5(x)=化简:1/log3(x)+1/log4(x)+1/log5(x)=l
化简:1/log3(x)+1/log4(x)+1/log5(x)=
化简:1/log3(x)+1/log4(x)+1/log5(x)=
化简:1/log3(x)+1/log4(x)+1/log5(x)=
log(a)(b)=log(c)(b)/log(c)(a)
原式=log2(3)/log2(x)+log2(4)/log2(x)+log2(5)/log2(x)
=log2(60)/log2(x)
=logx(60)
解不等式:log3/4(x+1)>log4/3(x-3)
化简:1/log3(x)+1/log4(x)+1/log5(x)=
log4[log3(log2x)]=0,求x^-1/2
2007*log5(1)+log4(27)*log3(4)
求证log3(4)=1/log4(3)
若x=24,则1/log2 (x)+1/log3 (x)+1/log4 (x)等于
若log3(x)=-1/log4(3),则x+x^2+.+x^n+.=
log3/4(x+1)>log4/3(x-3) 现在就要,
log3的2次乘以log4的x次=1 求x
解方程:log4{2log3[1+log2(1+3log2 x)]}=1/2
1/(2log3 4)=1/2·log4
log3(4)×log4(8)×log8(x)=log6(36)求X=?A.1/2B.6C.9D.18为什么等于Log3(x)a
log3 (log4 x)=0 对数方程,
解不等式:log3/4^(x+1)>log4/3^(x-3)要过程,都是分数为底,带字母为指数
已知log2[log4(log3x)]=log3[log5(log2y)]=0,求4更号x-y^1/5
已知log2[log4(log3x)]=log3[log5(log2y)]=0,求4更号x-y^1/5写过程
不等式log3/4(x+1)>log4/3 2的解集为?为什么 我把log4/3 2化成log3/4(1/2)后就算不出来了
比较log3 4与log5 6 大小还有log3 4与log4 5 的大小 看我做的 我用作商法 log4 5 ÷log3 4 =log4 5×log4 3 =log4 8=3÷2>1 ∴log4 5大于log3 4 帮忙看看错在哪里
