Just This? It's just affecting my work
He entered the examination hall, sat down, picked up the paper, and started working. At this time, Chen Fan wanted to finish it as soon as possible, get the reward, and go home.
The main thing was that Chen Fan didn't feel any joy.
" Let the real numbers a,b,c,d satisfy a > b > c > d0, and a b c d=1.
(a 2b 3c 4d)aabbccdd1.”
Chen Fan paused for a moment on the first question because it was very simple. Everyone had seen this question before.
Most of these questions were about positive real numbers. If they became real numbers, then the proof would not be simple and complicated.
This guy's thinking was a little strange. Something was going to happen.
Chen Fan looked at the rest of the examinees. Many of them started to write but stopped halfway.
Because he realized that the conditions were not good enough.
Chen Fan looked at Charlie and Tom on the podium. Charlie's face was full of sympathy, while Tom looked indifferent.
At this moment, Chen Fan realized that the world of mathematics was indeed vast.
But how can this affect the speed of my cooking?
He said he would get extra points, and he did.
This time, I'll still get 48 points. It doesn't matter who comes. Even if I say it, Jesus won't be able to stop me.
"Since the real numbers a, b, and c satisfy baic > dub > a > 0,
Then 1a >= zhi1b, 1a >= 1c,
ab2c3=a2b2c2ca> 13a2b2c2 (aa ba ca)
Since a b c=1a 1b 1c, aa ba ca=(a b c) 33a
≥13（1a 1b 1c）（1a 1b 1c），
Then 13a2b2c2 (aa ba ca)> 19a2b2c2 (1a 1b 1c) 2
=19（bc ac ab）2，
Since a b c=1a 1b 1c, that is, dao has abc (a b c)=ab bcca,
Since (a b c)(1a 1b 1c)>= 33 ü-abc33 ü-1abc=9,
That is,(a b c) 2> 9, that is, a b c> 3,..."
Chen Fan took a shortcut. He started with the positive real number and then used the points obtained from the positive real number to expand.
The key to this question was how to extract useful formulas from the known math questions and then apply them to the changed questions.
Real numbers, functions.
Chen Fan made a list of images and started to draw the dots.
The second algorithm.
Then, he thought about it and used the reverse method to prove it.
Perfect. Three was enough.
Next question.
At this time, Tom had already moved to Chen Fan's side and was dumbfounded.
The first question was difficult. It was very difficult. At least, when Tom saw the question, he felt that it was difficult. However, it still didn't stump this kid?
He was quite skilled.
The second question, the third question.
Chen Fan didn't feel any pressure at all.
"What should we do? Chen Fan seems to be able to get the points he needs.”
"You don't have to worry about that," said Tom."I naturally have a special topic for this kid.”
"Are you sure?"
"Of course. By the way, how are the students from the other examination halls?”
Charlie sighed.
Twenty countries, one hundred and twenty examinees, divided into three examination halls. After Charlie strolled around, he discovered a terrifying situation. It was blank, completely blank.
Other than a few special students who could write down some steps and marks, most of the students were blank and in a daze.
"Isn't it too much?"
Tom said," Mathematics is a game for a few people. No one will really study mathematics. Most of them will be engaged in mathematics branches after they reach university, such as computer science, probability and statistics, introduction to economics, etc. Who would do mathematics academic research?'
"That seems to be true. Seven or eight out of ten of my students will do this.”
Tom rubbed his hands and said," Don't worry. I don't like this kind of competition. I prefer to see a winner in mathematics. These five children, one from India and two from Germany, are indeed the birthplace of mathematics. They're still as good as ever in mathematics, but one from America.”
"Foreign students, you know."
"I, I feel that all of them have been wiped out. No wonder Harvard is so angry. They especially asked me to come and ask me to come up with the most difficult questions.”
The best way to solve the gap between the top students and the slackers was to prevent the top students from getting the scores they wanted.
After yawning, Tom and Charlie returned to the examination hall and came to Chen Fan's side.
Chen Fan was looking at the last question in silence.
He looked up at Tom, who smiled without saying a word.
Chen Fan gave this guy the middle finger. Shameless, as shameless as ever. In order to prevent himself from getting an extra score, he really went through a lot of trouble.
“1=1
196884=196883 1
**=** 196883 1
**=** ** 2*196883 2*1
Please try to explain it in mathematical terms. There are at least two ways.
The meaning of this question was very simple. Even if you used multiple methods, you wouldn't get more marks.
Chen Fan began to write the matrix.
Chen Fan knew an algorithm from the beginning. It was very easy to solve this problem by using a matrix.
Then, he changed the Ranubi equation.
It was another kind.
Then, Chen Fan looked at Tom and began to write about the demon horde.
This child had studied this damn thing before?
Magic groups, Mersenne primes, and twin prime numbers were known as the three big holes in mathematics.
This child, why was he studying the demon horde? No, there was no reason for this child to learn the demon horde. He should have deduced it himself.
After thinking for a moment, Chen Fan wrote down a series of strange symbols.
Charlie frowned. What the hell were these things?
Tom didn't understand either. What was written here?
What about the Summoner?
