Chapter 183: Do You Know How Many Ways To Prove Fermat’S Little Theorem? (35)
Lin Hao has mastered [Mathematics: Theorem Proving]. Proving Fermat's Little Theorem is a piece of cake for Lin Hao.
After just briefly scanning Xueer's proof process, Lin Hao discovered several fallacies.
Although Xueer has been influenced by her grandfather all year round, she has not fully understood many mathematical knowledge.
Regarding this, Lin Hao also felt a little pain in his head.
Xueer wanted Lin Hao to help find her mistakes and help solve Fermat's little theorem, but Xueer's entire proof was specious, and it was really troublesome to modify it.
After all, if you help Xueer correct the fallacy, then Xueer must ask Lin Hao for advice. In this way, no one knows how long it will be delayed.
Lin Hao pondered for a moment, looked at Xue'er and said, "Do you know how many ways there are to prove Fermat's little theorem?"
In Lin Hao's original world, there was a famous article called "Kong Yiji", in which Kong Yiji once asked, "Do you know how many ways to write fennel?"
Coming to Lin Hao, it became clear that there are several ways to prove 'Fermat's Little Theorem'.
When Xueer heard Lin Hao's words, her eyes flickered and she looked confused. She shook her head and said, "I...I don't know any of them."
Lin Hao smiled and said: "There are five ways to prove Fermat's Little Theorem. Among them, "Numbers are proved by "group theory" | 463 Fermat's Little Theorem is the simplest..."
After he said this, Xueer hurriedly said: "Brother, can you tell me the method of group theory?"
Lin Hao smiled slightly, what he was waiting for was Xue'er's words.
Taking the pen from Xue'er, Lin Hao started writing on the paper, and in a short time, half of the page was filled.
"It's proven, this is the method of group theory." Lin Hao said.
Xueer was stunned for a moment. She wanted to take the folder from Lin Hao but didn't.
"Brother, is this the end?" Xueer was a little doubtful.
After all, in Xueer's impression, even if her grandfather took her to try to prove it, it would still have to be four or five pages, but Lin Hao could do it in such a small half-page?
"It's done." Lin Hao nodded.
"Okay..." Xue'er took the paper, feeling a little doubtful.
"But since eldest brother said that the proof is complete, he probably won't lie to me." Xue'er thought to herself.
"Just take this piece of paper back and give it to your grandpa." Lin Hao urged Xueer: "Go quickly, lest your grandpa blame you for taking too long.
Under Lin Hao's urging (cgff), Xue'er also moved her steps, and finally turned around and waved to Lin Hao: "Brother, if there are any problems, I will come back to you!"
"Yeah!" Lin Hao nodded, but thought to himself: "Don't come to me if you have any problems. What's the point of a little girl asking a grown man like me every day?"
After seeing off Xue'er, Lin Hao looked at the time and saw that he had been out shopping for more than an hour and it was time to go back.
At first, Song Xingwei still had a smile on his lips, but gradually, the smile disappeared, and the emotion in his eyes was surprise.
Therefore, Song Xingwei set his sights on his granddaughter again. However, his granddaughter was born with a lively and active personality and had no connection with scientific research.
Now, Song Xingwei just hopes that his granddaughter can learn a little bit.
Feifei pursed her lips and said: "I often come to your house to eat, and I would be embarrassed if Yuwei had to cook in person every time. 11
"You're really hitting me!" Xia Bing said angrily, covering her head.
Just like some time ago, the history teacher assigned an assignment of visiting a museum. This girl actually ran into the antique city where there was a mixture of good and bad people. Fortunately, there was no trouble.
In the scientific research community, Song Xingwei is definitely a well-known figure.
"Xue'er is back?"
"Grandpa, I'm home!"
"You are the only one who talks a lot!"
Xueer looked at Song Xingwei and curled her lips and said: "Grandpa, didn't you say that it would take me at least five days to solve Fermat's Little Theorem? I solved it today!
Footsteps sounded, and Liu Yuwei walked over, holding a small pot of cherries in her hand, looking quite leisurely.
In another villa, Xueer opened the door, then tossed her shoes and jumped into the house.
Lin Hao smiled, "Oh, it's rare that it's lunch time today, Yuwei is quite leisurely!"
Seeing Xue'er, Song Xingwei showed a kind smile. He still loved his granddaughter very much.
"Okay, it's good to have this awareness." Lin Hao said with a smile.
Feifei picked up a steel spoon on the table and hit Xia Bing on the head.
Seeing this scene, Lin Hao couldn't help but be stunned.
Xue'er sat next to Song Xingwei, "I'm not bragging. If I say I can solve it, I'll solve it!"
Looking down, Xueer's grandfather really looks like an old intellectual.
"How is it? Did you solve the problem assigned to you?" Song Xingwei said.
In fact, Xueer's grandfather is really an old intellectual. Song Xingwei is a professor in the Department of Mathematics of Shanghai Jiaotong University and an academician of the Chinese Academy of Sciences. He has made many outstanding contributions in the field of mathematics research in China.
Feifei shouted: "Yuwei, Lin Hao is home!"
"Four kinds?" Xue'er asked doubtfully, "Isn't it five kinds?"
Xia Bing stuck her head out and interjected: "Actually, my cousin learned how to cook a few dishes and wanted everyone to try them, especially Lin Hao. My cousin said that if a chef like Lin Hao can find it delicious, then Her kung fu is perfect.”
As soon as I walked in the door after returning home, a smell of rice came over me, and I saw Feifei wearing a pink apron carrying dishes to the table.
"Oh?" Song Xingwei said with a smile: "Don't brag."
"Could it be that this little girl really solved it?" Song Xingwei asked: "There are four ways to prove Fermat's little theorem. Which one did you use?"
It is a pity that Song Xingwei's son eventually worked in the financial industry. Although he has made a great career and has amazing assets, it has always been Song Xingwei's regret that his son did not make any contribution in the field of mathematics.
After taking Xueer's folder, Song Xingwei began to read the proof process written by Lin Hao.
He really wants his children to inherit his knowledge and continue to shine on the road of scientific research.
Song Xingwei was dumbfounded, thinking in his mind that Xue'er might have made another paradoxical mistake.
As a famous Chinese mathematician, there are not many things in the field of mathematics that can surprise Song Xingwei...
Xueer's grandfather was sitting in front of the coffee table, looking up information on the computer and writing a few strokes in the tome at hand.
The decoration of Xueer's home has a Chinese classical feel. After passing through a mahogany entrance and turning around, there is a coffee table in front of the floor-to-ceiling window, with a computer on it, and large books on the surrounding bookshelves.
