Xiao Huanxi: I Broke God's Forbidden Zone

The third big question.

Still can't pick out any faults, all right!

Fourth big question.

Still totally right!

Zhao Jian became more and more frightened as he changed his mind. His ideas for solving problems were clear, and the formulas he wrote were not at all superfluous.

This pottery fruit is definitely not easy!

Could it really be that he failed to solve the problem in ten minutes?

Zhao Jian's heart was full of shock and doubts.

Other teachers felt the same way, and some couldn't help but ask:

"Mr. Li, is this...really made by Tao Cheng in ten minutes?"

Li Meng smiled slightly: "This can still be fake. There are hundreds of pairs of eyes staring at Chunfeng Middle School. If you don't believe me, you can go and find out."

All the teachers sucked in a breath of cold air and felt their scalps go numb.

To make such a perfect answer in ten minutes, even if you don't get full marks, is enough to shock the Chinese college entrance examination community.

Zhao Jian lit a cigarette and took a deep breath.

This guy, won't really get a perfect score...

Chapter [-] You are not worthy to be his opponent

Zhao Jian squeezed the cigarette butt into the ashtray and began to cheer up the fifth question.

then……

The fifth big question still can't pick out any faults!

He frowned, and he already had a bad premonition in his heart: this kid named Tao Cheng might actually get full marks!

Now, on to the most critical problem!

This question has exceeded the outline of high school mathematics, and several famous scholars from the three schools have fallen under this question:

已知函数F(x)=1/√(1+x)+1/√(1+a)+√ax/(ax+8)；xEUR(0,+∞)。；

1. When a=8, find the monotonic interval of f(x);

2. For any positive number a, prove that 1<f(x)<2.

The title of this question looks very simple, and the first question is not difficult. You can directly derive the increasing interval (0,1] and the decreasing interval [1,+∞).

The real difficulty of this question is the second question. When proving 2<f(x), we need to prove that the arithmetic mean of two positive numbers is not less than the geometric mean.

This is the only solution that does not exceed the class, but it is also a very partial knowledge point.

So it was wrong for other teachers to say that this question was beyond the syllabus at first, because this question can be proved by a method that does not exceed the syllabus.

This is also the genius of the propositioner, Huo Lao Huo Pingzhi, but most math teachers simply cannot understand it.

This is where the last big question goes beyond the outline.

When proving f(x)<2, it is very skillful to classify and discuss the two cases of a+b, a+b<7 and a+b≥7, which even greatly exceeds the difficulty of the Olympiad problem.

So high school students can't imagine it, and it's very difficult to understand.

Even the gold medal math teachers present, such as Zhao Jian, Li Meng, and the others, if they don't have an answer, they basically can't figure it out.

Even if you look at the answer, you have to analyze it for a long time before you can understand it.

Therefore, in today's grading so far, no one can really get close to the second question of this question, even Qian Sanyi only barely proved 2<f(x).

As for the verification of f(x) < 2, Qian Sanyi wrote a lot, but in fact it didn't touch it at all. Only two points are deducted.

This is why Li Meng said at the beginning that Tao Cheng would finish this set of papers within ten minutes, and most likely it was a full score. All the teachers didn't believe it, and Zhao Jian even scoffed.

Zhao Jian raised his glasses with a dignified expression, and began to look at the answer seriously while watching Tao Cheng's problem-solving process.

The first question is relatively simple, and they can basically do it at the level of a scholar like them.

Therefore, Tao Cheng's answer to the first question is also perfect, and he can't pick out any faults.

All the teachers were not surprised by Tao Cheng who did everything right.

The real problem, the second question came, and all the teachers held their breath.

This is related to whether anyone in the three schools can do it. If they can't do it, this question is equivalent to a waste question.

Presumably, Mr. Huo, who asked the question this time, would also be quite unhappy.

Problem solving begins: for any given a>0, x>0, by f(x)=......

......

There are some discrepancies between Tao Cheng's answer and the answer given by Mr. Huo, so the teachers couldn't understand it for a while, and they joined the discussion one after another...

Gradually, the whole idea became clearer, and they were surprised to find that Tao Cheng's problem-solving was simpler than that of Mr. Huo's.

This question has a high conception, deep meaning, and a wide entry. Therefore, although it is difficult to solve the problem, there are many ways to solve it.

At the end, all the teachers were sweating profusely, feeling that half of their brain cells were dying...

The entire math group was in a dead silence, and needles could be heard falling.

After a long time, Zhao Jiancai let out a sigh of relief:

"Genius, just genius!"

At this moment, he finally had to accept: in front of Tao Cheng, Qian Sanyi can only be regarded as a good student.

The other teachers also gradually understood, and their backs felt chills unconsciously... Is this really something a high school student can do?

And it takes ten minutes for all the questions, so this question will not take more than three minutes!

Even if it was them, it would probably take half a day to figure it out.

All the teachers were terrified, dumbfounded, and their faces were full of disbelief!

For a time, the teachers began to scrambling to learn about Tao Cheng from Li Meng:

"This... was it really made in ten minutes?"

"A genius like Tao Cheng should be very famous, how come I've never heard of this person?"

"Yes, yes, what is the origin of this Tao Cheng?"

"..."

Li Meng just had a smug smile on her face and was about to answer.

I don't want a female doctoral teacher in Chunfeng Middle School who has just joined the job, only to understand Tao Cheng's answer, wake up from meditation, and exclaimed:

"He...he did everything right!"

The other gold medal teachers smiled bitterly, you just saw it.

The young female teacher looked excited:

"Full score! Tao Cheng full score!"

Unexpectedly, a surprised voice came from outside the door:

"Full score?!"

The teachers in the math group were taken aback for a moment, thinking that the others had heard the voice of the young female teacher and repeated in surprise.

But I didn't expect that there was a vaguely surprised voice from other directions:

"Full score!"

"Full score!"

......

Full score? !

Is it?

The teachers in the math group couldn't sit still and started running towards the marking hall...

Chapter [-] The results of the three-school joint entrance examination are out!

Full score!

All full marks!

language!English!Li Zong is full score!

With that said...

Isn't Taocheng a full score? !

Over the years since the establishment of the three schools, Taocheng is the first to get a full score!

This is unprecedented, and it is estimated that there will be no future!

All the people present took a deep breath, and their chins were about to hit the soles of their feet!

There is a monster in Chunfeng Middle School!

Zhao Jian smiled bitterly, Sany, Sany, you have a formidable opponent.

wrong!

Maybe......

You don't deserve to be his opponent...

......

Tao Cheng got the first full score in the history of the three schools.

Like a hurricane, this news quickly spread among the teachers of the three schools' examination group.

Almost all senior high school teachers know that there is a monster in Chunfeng Middle School!
