I think too much upstairs.
This topic is not small:
Chen Ran is an associate professor in the Department of Mathematics of a well-known university. Students call to ask a question: If 1=5, 2=25, 3= 125, 4=925, then 5=?
Chen Ran read the topic carefully, hoping to find the mystery. Finally, we can only follow the power law. 1 equals to the first power of 5, 2 equals to the second power of 5, 3 equals to the third power of 5, and so on. Then 5 is the fifth power of 5 and should be equal to 625, but in this case, 4 should be equal to 625, not 925.
"Look at the topic carefully, 4 should be equal to 625, not 925." Chen Ran dialed the telephone of the student.
"4 is really equal to 925. This is an international Olympic mathematics competition, and the topic itself should not be a problem. " The students checked the original question and said for sure.
Chen Ran thought hard for half an hour again, but there was still no result. He decided to ask Professor Zhu, his tutor when he was a graduate student, for help. Professor Zhu wrote down the topic and said that he would call him back as soon as he had the answer.
Forty minutes later, Professor Zhu called: "Are you mistaken? 4 should be equal to 625, not 925! In this case, 5 should be equal to 3225! "
"Teacher, the topic is indeed 4 equals 925. I am not mistaken." Chen Ran replied.
"If so, then this topic should be a brand-new topic in the digital field, which deserves our in-depth study and discussion." Professor Zhu said excitedly.
Put the phone down, those numbers have been lingering in Chen Ran's mind, and he is sitting alone in the living room. When his wife Xiaoli came back from the night shift, the couple took over the topic and studied it together.
"Mom, are you ready for the midnight snack?" My son, who is in the sixth grade, came out of the room.
"Wait a minute, mom is busy now." Xiaoli said.
The son leaned forward and saw that it was a math topic. He glanced at it and said disdainfully, "What is there to study on such a simple topic?"
"Simple? The human breath is very small. How much is 5? " Chen Ran said unhappily.
"1 equals 5, no matter how many 2, 3 and 4 are equal to it, 5 equals 1. I really don't know how you were named as an associate professor. The biggest problem for you adults is that you like to think simple things are particularly complicated. " The son smiled contemptuously and said.
