Lin Fan glanced at the system list, closed his eyes, and fell asleep deeply.
……
The next day, a ray of warm sunrise lightly spilled into the 104 dormitory through the window.
"Jingle Bell!"
At almost the same time, three different bells rang in the bedroom.
Then, Ma Zhong, Song Yi, and Zheng Jinbao, who had been asleep, sat up from the bed together and quickly dressed.
Lin Fan couldn't help but wonder: "What's wrong with you?"
Yesterday, they had been chirping for a long time before they got up reluctantly.
Today, it's just like two people.
"Teacher Tiantian's class is teacher Tiantian's class!" Zheng Jinbao exclaimed.
Lin Fan is still puzzled, but he still dresses and washes.
Walking on the way to the classroom, Lin Fan watched the anxious steps of the three and asked, "Is this teacher Tiantian's class important?"
"Important! Too important! If I don't see Teacher Tiantian for a day, I feel uncomfortable!" Zheng Jinbao said.
Song Yi said: "Brother Fan, hurry up! Otherwise, there will be no seats later."
No seats?
University classrooms are very wide.
Lin Fan has been in class for the past two days, and there have been many seats in the classroom.
Today, will there be no seats?
Lin Fan finally came to the classroom with full of doubts.
It was only then that he didn't understand why Song Yi and others said that.
There are still more than ten minutes before class.
But, the classroom is already covered in black, and it's all people.
Zheng Jinbao pointed to the last row and said excitedly: "There are four seats left. Let's go over there quickly. Don't be occupied."
When Lin Fan and others sat down, all the seats were filled.
And those who entered the classroom again, after seeing the seating situation, had no choice but to sigh and leave.
Lin Fan asked, "Why are there so many people in this teacher's class?"
"You'll find out later." Song Yi said excitedly.
"Jingle Bell!"
At this time, the class bell rang.
In an instant, the classroom that was originally noisy, instantly calmed down like a needle.
"Tap!"
A burst of crisp footsteps, from far to near.
Soon, a superb beauty came to the podium.
She has a handful of beautiful hair like a waterfall, a pretty face that can be broken by blowing, with the willow eyebrows, red phoenix eyes, little Qiong nose, and a smart little cherry mouth carefully portrayed by God.
A white dress outlines her perfect figure (oYo).
Plus, there is a special charm that she exudes...As long as people take a look, they can't move their heads at all.
Lin Fan did not disable the real eye and started to observe.
Value: 98
Favorability: 60
98's face value!
Nearly full marks!
Shen Yu Luo Yan, closed moon and shame flowers. Perhaps it means she is.
It's no wonder that the classmates are so anxious to come to her class.
Favorability, 60? Reached the 60-point pass line! She seems to have a good impression of herself?
Is this a teacher who treats every student as a friend?
At this time, Hu Tian, standing on the podium, said: "Today, we will continue to explain higher algebra..."
Her voice is the same as her name, very sweet and full of magnetism, so people don't want to miss even a word.
After a while, Hu Tian wrote a question on the blackboard: Find all prime numbers p, q, r, and make p^q+p^r a perfect square number.
"Everyone can try to answer it." Hu Tian said.
All the students immediately picked up their pens and continued to write on the draft paper.
They thought of using the shortest time to solve the problem, and thus got Hu Tian's attention.
However, soon, all the students scratched their heads.
Because they don’t know how to answer.
Zheng Jinbao said anxiously: "Ma Zhong, haven't you answered it yet? It's been so long!"
Ma Zhongdao: "Don't worry!"
"Don't be preempted! If Ma Zhong can't answer, then I hope everyone won't answer!" Song Yi prayed silently.
Hu Tian, with bright eyes like water, glanced around the classroom, seeming to be looking for someone who can answer the question.
Unfortunately, no one raised their hands to answer the question.
So Hu Tian said, "Lin Fan, can you come up and answer it?"
Lin Fan slowly stood up.
Suddenly, the eyes of all the students fell on Lin Fan.
That is envy, jealousy!
Lin Fan didn't understand why this Hu Tian would suddenly call her own name.
I didn’t seem to raise my hand either?
Lin Fan first glanced at the title on the blackboard and thought about it for a while, then walked to the podium and picked up the chalk to quickly write.
If q=r, then p^q+p^r=2p^q, so p=2, q is a prime number.
Therefore (2, q, q) is a ternary prime array that satisfies the conditions...
……
In summary:
(2, 2, 5), (2, 5, 2);
(3, 2, 3), (3, 3, 2);
(2, q, q), (q》=3)
Soon, a lot of calculations were written on the blackboard, and finally the answer was reached.
Hu Tiantian said: "The answer is very correct, and it is easier than the calculation method I thought ."
Lin Fan said: "However, this is still not the easiest way to solve problems."
"Oh?" Hu Tian immediately became interested.
Then, under Hu Tian's expectant gaze, Lin Fan wrote a nearly half-simplified problem-solving step.
After seeing Hu Tian, her beautiful eyes lit up, and she exclaimed: "I can't imagine that prime numbers can be calculated like this..."
After pondering a little, Hu Tian said again: "If you use this method, maybe..."
Hu Tianqing couldn't help writing on the blackboard quickly.
Q=p1m1+b1=p2m2+b2……pkmk+bk
Q=41=2m+1=3m+2=5m+1
……
Not long after, Hu Tian stopped the chalk in her hand.
Then, looking for help, he looked at Lin Fan.
Lin Fan said: "Twin prime number conjecture?"
Since he got professor-level mathematics experience, he has read a lot of mathematics-related materials, and of course he knows the world-class problem-the twin prime conjecture.
Hu Dessert nodded and said: "Yes."
Lin Fan picked up the chalk and put it under Hu Tian, and quickly started writing.
However, even if Lin Fan has professor-level mathematics experience, coupled with absolute concentration, if he fails to trigger a flash of 5% aura, he will not be able to solve the twin prime conjecture.
After a while, Lin Fan also stopped.
Hu Tian said: "The above calculation, if replaced by p^q+xb=3m+2...what do you think?"
Lin Fan thought for a while, shook his head and said: "No, it's 5p5m+p^q..."
While discussing, the two of them wrote the steps to solve the problem.
Soon, the whole blackboard was filled with dense calculations.
