log3*2/log9*4=?
log3*2/log9*4=?
log3*2/log9*4=?
等于1
log6/log36
=lg6/36
=lg1/6
=-lg6
1)没有括号：log3*2/log9*4=(log3)*2/(log9)*4=(log3^2)/(log9)*4=(log9)/(log9)*4=4
2)可能1：log(3*2)/log(9*4)=log(6)/log(36)=log(6)/log(6^2)=log(6)/[2log(6)]=1/2
3)可能2：log3*2/(log9*4)=(log3)*2/(4log3^2)=2log3/(8log3)=log3/(4log3)=1/4
.................
log3*2/log9*4=?
log3*2/log9*4
为什么log9 (9/2)=log3(81/4)
化简(log3 4)/(log9 8)
log5[log2(log9/log3)]=?
为什么log9(2)=log3(2)/2如题
(log3^2 + log9^4)×(log4^3 + log8^3)
log 243÷log9 =log3^5÷log3^2 =log3^5-log3^2 然后怎么写
已知log3(4)=a,log3(5)=b 则log9(16/25)=
已知log3(4)=a,log3(5)=b 则log9(16/25)=
(log2(3)+log8(9))x(log3(4)+log9(8)+log3(2))
求（log2^3+log8^9)(log3^4+log9^8+log3^2)的值
log3 5-log3 15+1/2log9 27 的值
（log2 3+log4 27）*（log3 4+log9 8）=log2的2是下标,后同
求x,y值.6log9^x+3log27^y=8log3^x+2log9^y=2
log3^2*log5^7/log9^1/7*log125^82.log2^3=1-a/a,则log3^12=
(log3,4+log9,4)log4,3—log2,2根号2 这怎么解答了
已知Log9(8)=a,则Log3（2）=?用a表示
