化简:1/log3(x)+1/log4(x)+1/log5(x)=

化简:1/log3(x)+1/log4(x)+1/log5(x)= 已知log2[log4(log3x)]=log3[log5(log2y)]=0,求4更号x-y^1/5 2007*log5(1)+log4(27)*log3(4) log4[log3(log2x)]=0,求x^-1/2 解不等式：log3/4(x+1)>log4/3(x-3) log4(log5 a)=log3(log5 b)=1,求a/b. log5 1/3*log3 6*log6 X=2,则x等于多少 有关log的数学题①log2(2X+3)=0②log5(X)-1/3log5(8)=0③log2(X)+log4(X)= 若log3^5 log5^7 log7^x=log4^2 log6^4 log8^6,求x=? 解方程log4 x+1/log4 x=10/3 log3/4(x+1)＞log4/3(x-3) 现在就要, log4(3x-1)-log4(3+x)=log4(x-1)
