Lin Fan glanced at the system list, closed his eyes, and fell into a deep sleep.

The next day, a ray of warm morning sun lightly poured into the 104 dormitory through the window.

"Jingle!"

At almost the same time, three different bells rang in the bedroom.

Next, Ma Zhong, Song Yi and Zheng Jinbao, who were sleeping soundly, sat up from the bed together and quickly dressed.

Lin Fan couldn't help but wonder, "What's wrong with you guys?"

Yesterday, they chirped for a long time before they reluctantly got up.

Today, it's like a different person.

"Teacher Tiantian's class is Teacher Tiantian's class!" Zheng Jinbao exclaimed.

Lin Fan was still puzzled, but he continued to dress and wash.

On the way to the classroom, Lin Fan looked at the anxious steps of the three and asked, "Is this Teacher Tian's class important?"

"Important! It's so important! I don't see Teacher Tiantian for a day, and I feel sick all over!" Zheng Jinbao said.

Song Yi said: "Brother Fan, hurry up! Otherwise, there will be no seats later."

No seats?

College classrooms are very spacious.

Lin Fan has been in class for the past two days, and there have been many empty 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 understood why Song Yi and others said that.

There are still ten minutes before class.

However, the classroom is already dark and full of people.

Zheng Jinbao pointed to the seat in the last row and said excitedly: "There are still four seats there, let's go, let's hurry up and don't be occupied by others."

When Lin Fan and the others sat down, all the seats were filled.

And those who entered the classroom again had no choice but to sigh and leave after seeing the seating situation.

Lin Fan asked, "Why are there so many people in this teacher's class?"

"You'll find out later." Song Yi said excitedly.

"Jingle!"

At this moment, the school bell rang.

In an instant, the originally chaotic classroom was as quiet as a needle fell.

"Tap Ta Ta!"

A crisp footstep sounded from far to near.

Soon, a superb beauty walked to the podium.

She has a handful of waterfall-like hair, a pretty face that can be broken by a bullet, with willow eyebrows, Danfeng eyes, Xiao Qiong nose, and a clever cherry mouth.

A white dress framed her perfect figure (oYo).

In addition, she exudes a special charm... As long as people look at it, they can't move their heads at all.

Lin Fan observed without using the Eye of Truth.

Appearance: 98

Favorability: 60

98 looks!

Almost perfect!

The fish and geese fall, the moon is closed and the flowers are ashamed. Maybe it was her.

It's no wonder that the students in the class are so anxious to come to her class.

Favorability, 60? Reached the passing line of 60 points! Does she seem to have a good opinion of herself?

Could it be that this is a teacher who treats every student as a friend?

At this time, Hu Tian, ​​who was standing on the podium, said: "Today, we will continue to explain advanced algebra..."

Her voice, like her name, is sweet and magnetic, making people not want to miss a word at all.

After a while, Hu Tian wrote a question on the blackboard: Find all prime numbers p, q, r so that p^q+p^r is a perfect square.

"Everyone can try to answer." Hu Tian said.

All the students immediately picked up their pens and started writing on the scratch paper.

They thought of solving the problem in the shortest time, so as to get Hu Tian's attention.

However, soon, all the students scratched their ears.

Because they don't know how to answer.

Zheng Jinbao said anxiously, "Ma Zhong, haven't you solved it yet? It's been so long!"

Ma Zhong said: "Don't worry!"

"Don't be preempted! If Ma Zhong can't answer, then I hope no one can answer!" Song Yi prayed silently.

Hu Tian glanced around the classroom with eyes as bright as water, as if looking for someone who could answer the question.

Unfortunately, no one raised their hand to answer the question.

So, Hu Tian said, "Lin Fan, can you come up and answer it?"

Lin Fan slowly stood up.

Immediately, the eyes of all the students fell on Lin Fan.

That's envy, jealousy!

Lin Fan didn't understand why Hu Tian suddenly called her name.

You don't seem to raise your hand, do you?

Lin Fan first looked at the title on the blackboard and thought for a moment before walking to the podium and quickly writing with chalk.

If q=r, then p^q+p^r=2p^q, so, p=2, q is a prime number.

So (2, q, q) is a ternary prime array that satisfies the condition...

In summary:

(2,2,5),(2,5,2);

(3,2,3),(3,3,2);

(2, q, q), (q"=3)

Soon, the blackboard wrote a lot of calculations, and finally came up with the answer.

Hu Dian said: "The answer is very correct, and it is simpler than the calculation method I thought ~IndoMTL.com~."

Lin Fan said, "However, this is still not the easiest way to solve the problem."

"Oh?" Hu Tian immediately became interested.

Next, under Hu Tian's expectant gaze, Lin Fan wrote down the half-simplified problem-solving steps.

After Hu Tian saw it, her beautiful eyes lit up slightly, and she said with admiration, "I can't believe that prime numbers can be calculated like this..."

After pondering for a while, Hu Tian said again: "If this method is used, maybe..."

Hu Tianqing couldn't help but write quickly on the blackboard.

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 gained professor-level mathematics experience, he has been reading a lot of mathematics-related materials, and of course he knows the world-class problem - the twin prime conjecture.

Hu Diantian 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 the 5% flash of inspiration, he will not be able to solve the twin prime conjecture at all.

After a while, Lin Fan also stopped.

Hu Tian said: "If the above calculation is replaced by p^q+xb=3m+2...what do you think?"

Lin Fan thought for a while, then shook his head and said, "No, I'll change it to 5p5m+p^q..."

The two discuss and write down the steps to solve the problem.

Soon, the entire blackboard was filled with dense calculations.
