你这人……一点分都不不给还说话这么不客气,什么“我要详细过程 今晚就要”!
真不愿意理你~不过看在你这题目有点意思的份上,还是给你回答了吧!
㏒根号2+㏒3-㏒根号10／㏒1.8
=log(3根号2)-㏒根号10/log1.8
=log(3根号2)-0.5/log1.8
=log(3根号2)-0.5/log(18/10)
=log(3根号2)-0.5/(log18-log10)
=log(3根号2)-0.5/(log18-1)
=log(3根号2)-0.5/(log(（3根号2）的平方)-1)
=log(3根号2)-0.5/(2log(3根号2)-1)
这下只要求出log(3根号2)带进去就行了,好像不能再化简了.
答案≈-1.331
