Lin Fan glanced at the system list, closed his eyes, and fell asleep.

...

The next day, a ray of warm morning sun lightly poured 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 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, they are two different people.

"Mr. 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 watched the anxious steps of the three and asked, "Is this Teacher Tian's class important?"

"Important! It's so important! I'm sick all over without seeing Teacher Tiantian for a day!" Zheng Jinbao said.

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

No seat?

University 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.

Will there be no seats today?

Lin Fan finally came to the classroom with full of doubts.

It was only now that he understood why Song Yi and others said that.

There are still ten minutes before class.

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

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

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

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 Bell!"

At this moment, the class bell rang.

In an instant, the originally chaotic classroom was as silent as a needle falling.

"Tap Tap!"

A burst of crisp footsteps, from far to near.

Soon, a superb beauty came to the podium.

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

A white dress that outlines her perfect figure (oYo).

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

Lin Fan couldn't help but observe with the Eye of Reality.

Face value: 98

Favorability: 60

98 looks!

Almost perfect!

Sinking fish and geese, closing the moon and embarrassing flowers. Maybe it was her.

It is 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?

Is it,

Is this 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, and 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 hands 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, that's jealousy!

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

You don't seem to have raised your hand?

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 \u003e = 3)

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

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

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

"Oh?" Hu Tian immediately became interested.

Then, 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 Tian couldn't help but write quickly on the blackboard.

Q=p1m1+b1=p2m2+b2……pkmk+bk

Q=41=2m+1=3m+2=5m+1

...

It didn't take long for Hu Tian to stop the chalk in her hand.

Then, he looked at Lin Fan with his eyes asking for help.

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, it's 5p5m+p^q..."

The two discussed and wrote the steps to solve the problem.

Soon, the entire blackboard was filled with dense calculations.
