姜老师，您解答特别清晰！忍不住再问问您哈，这道题问第一类定义即可：化简就是x = z，不可以的原因是不是原题中说X是所有不为0得数，而不为0包括1，所以Z不能是1这个就不满足了，所以I不行，对吗？谢谢啦

In a meeting of 3 representatives from each of 6 different companies, each person shook hands with every person not from his or her own company. If the representatives did not shake hands with people from their own company, how many handshakes took place?
姜老师，这道题我读到信息是：六家公司，每个公司出3个代表，没个代表跟别家公司代表握手，不跟自己公司握手，一共多少次握手。所以每个公司三个代表，每个代表都去另外那五个公司分别和里面代表握手，就是3^5，又因这个公司三个代表，就是3*3^5=就错了....我另一个思路，一个人握手的次数是（3*5），又因为一个公司三个人，3*（3*5）=45 还是不对 我您看我哪里出了问题。谢谢
