急 数学 求 （log3 2+log9 2）-（log4 3+log8 3）

答：
（log3 2+log9 2）-（log4 3+log8 3）
=log3(2)+log9(2)-log4(3)-log8(3)
=log3(2)+log3(2)/log3(9)-log3(3)/log3(4)-log3(3)/log3(8)
=log3(2)+(1/2)log3(2)-1/[2log3(2)]-1/[3log3(2)]
=(3/2)log3(2)-(5/6)/log3(2)
怀疑中间不是减号，而是乘号：
（log3 2+log9 2）×（log4 3+log8 3）
=[log3(2)+log9(2)]×[log4(3)+log8(3)]
=[log3(2)+log3(2)/log3(9)]×[log3(3)/log3(4)+og3(3)/log3(8)]
=[log3(2)+(1/2)log3(2)]×{1/[2log3(2)]+1/[3log3(2)]}
=[(3/2)log3(2)]×[(5/6)/log3(2)]
=5/4

要怎样才能提高学数学的思维。急

上课时思维要紧跟老师，要大声的回答问题，思维要开放一些，一般的数学新知识都是把他转换成旧的知识可以解答出来的，另外就是多看一些典型的例题，记住要典型，坚持自己做题，不会做题先使劲想会，如果实在不会就让同学给你点一下题，记住不要让他说完。然后自己做，这样你的数学一定会学好
