Fermat's theorem, also known as Fermat's final theorem, is known as the three major problems of human mathematics together with the four-color conjecture and Goldbach's conjecture.

This was proposed by the great French mathematician Fermat in 1637.

Fermat asserted that when an integer

>2, the equations x^ for x, y, z

+ y^

= z^

There is no positive integer solution.

As soon as this theorem was proposed, it immediately aroused great interest in the world mathematical community, and in the following three hundred years, generations of mathematical masters devoted their lives to it.

However, it has never been able to overcome it, and the difficulty of proving can be imagined.

This guy Li Jiaxing actually asked Qiao Tianyu to prove Fermat's theorem, which is indeed a bit too much!

"What's the matter, you're scared?" Li Jiaxing saw that Qiao Tianyu was silent, raised his head and laughed.

"Haha, Qiao Tianyu, weren't you pretty awesome just now? Didn't you make me unable to get off the stage? You have the ability to prove it, come on, prove it!"

This guy!

It's really shining when you give him some sunshine!

In the face of Li Jiaxing's provocation, Qiao Tianyu was not angry, and still maintained the smile just now.

"Li Jiaxing, don't just talk about me first, you tell me, Fermat's theorem, how far have you proved it?"

As soon as he heard Qiao Tianyu ask him about the progress of the proof, Li Jiaxing naturally would not let go of this good opportunity to pretend to be forced.

He couldn't wait to come up with his latest proof and said triumphantly.

You know, it's only been two years since I proved this theorem, and I've proved it to 60%, and in two years at most, I'm sure I'll be able to overcome Fermat's theorem!"

"Oh, 60% progress in two years, it's not slow. Qiao Tianyu nodded.

Li Jiaxing is worthy of being a leader in the world of mathematics today, and it is indeed not easy to have such achievements.

"But even at the fastest speed, it will take you 4 years to solve Fermat's theorem, how much time are you going to give me to prove it?"

"I don't care about this, when you prove it, I will follow you whenever it comes, but the premise is that you have to prove it before me, otherwise as soon as my paper is published, your proof will be meaningless!" Li Jiaxing said proudly.

"You said it yourself!" Qiao Tianyu hurriedly said.

"As long as I can prove Fermat's theorem before you do, you'll come with me, and this time you'll no longer be cheating, right?"

"Of course!

Li Jiaxing naturally didn't believe that Qiao Tianyu could prove this world's history-level problem, so he slapped his chest thumping.

"There is no basis for words, so let's use words as evidence. Qiao Tianyu picked up a pen and paper from the desk and drafted a letter of guarantee.

Li Jiaxing didn't even think about it, and happily signed his name on it.

"Okay, get out of the way. Qiao Tianyu waved his hand and coaxed Li Jiaxing out of his seat.

He sat down, picked up a pen and paper, and wrote, "A cup of black coffee, strong, thank you!"

"Hey, hey, what are you doing?" Some of the monks in Li Jiaxing were confused.

"Write a proof of Fermat's theorem!"

Qiao Tianyu threw Li Jiaxing a meaningful smile, and then lowered his head and continued to write proof.

"Just kidding!" Li Jiaxing muttered quietly.

"If you can prove Fermat's theorem, I'll call you grandpa!"

After speaking, Li Jiaxing took the scratch paper and went to the other table to make a proof.

"Hey, hey, grandson!" Three hours later, Qiao Tianyu slapped a stack of draft papers for the calculation in front of Li Jiaxing, "Come on, call grandpa!"

"What grandpa?!"

Li Jiaxing glanced at Qiao Tianyu, lowered his head and began to study Qiao Tianyu's proof process.

Qiao Tianyu knew the proof process, and he couldn't finish it in three or five hours, so he left Li Jiaxing and went out to find a place to eat.

After working for most of the day, my stomach has already sung the empty city plan.

More than an hour later, Qiao Tianyu, who was full of wine and food, returned to the research room with a bag of fried chicken burgers.

But as soon as he pushed the door in, suddenly a figure pounced on him with lightning speed and knelt in front of Qiao Tianyu with a pop.

"Grandpa, I'm convinced! Your proof is no problem! I'm really convinced!"

At this time, Li Jiaxing admired Qiao Tianyu and threw himself to the ground, except for kneeling and worshiping, there was nothing to express his excitement at the moment.

"Haha, good grandson, just take it!"

Qiao Tianyu was very satisfied with Li Jiaxing's attitude of admitting his mistake this time, and threw the fried chicken burger to him.

"How about it, come with me?"

"Let's go, let's go!"

Li Jiaxing hurriedly packed his bags and became Qiao Tianyu's little follower with all his heart.

Since then, Li Jiaxing, one of the "Qiao's Four King Kongs", has been successfully incorporated by Qiao Tianyu.

In fact, this time, Qiao Tianyu cheated.

Although Qiao Tianyu's proof of Fermat's theorem is absolutely accurate, this proof is not from Qiao Tianyu, but from the great British mathematician Andrew Wiles.

At 11:04:11 on October 25, 1994, Wiles sent a complete proof of Fermat's theorem to the world mathematical community through his student Carl Lubbin.

Later, it was verified and confirmed by the world's mathematical community, so far mankind has finally conquered Fermat's theorem after more than 300 years.

This event can be described as a milestone event in human history, and the whole world celebrates it.

And Qiao Tianyu, a mathematics enthusiast, was naturally also overjoyed, and watched the proof process over and over again, and was familiar with it.

So today, Qiao Tianyu had no choice but to "steal" Wiles's research results in advance.

However, Qiao Tianyu and Li Jiaxing repeatedly emphasized that the process of proving Fermat's theorem should not be disclosed to anyone.

Qiao Tianyu still left this honor to Wiles, which can be regarded as a tribute to this mathematical giant!
