Chapter 50
The next day, after having lunch and resting for an hour, the second test of the number couplet came as scheduled.
Just like yesterday, I entered the examination room 15 minutes in advance, prepared the answering tools, and waited quietly for the arrival of the examination bell.
At 2 o'clock sharp, the second exam of the number couplet officially began.
Qin Luo had made preparations a long time ago, picked up the test paper and saw that there were only three questions.
But the invigilator gave a full three pieces of draft paper.
The first question, geometry question, 15 points.
The second question, algebra question, 15 points.
The third question, the calculation of pure sequence, 30 points!
A total of 60 points!
There has always been a rule in mathematics examinations, that is, the higher the score, the more difficult the examination.
This seemingly ordinary sequence problem is the most difficult one.
Pick up a pen to solve the problem.
first question!
Well, although it is the easiest question on the test paper, it is enough to scare away 99% of the candidates in the country.
This is truly a test for geniuses!
A right-angled trapezoid is drawn on the test paper, and there are three lines of P, M, and Q outside the figure. It is required to prove that PMQ is perpendicular to the trapezoid.
The trapezoid intersects with the square, various lines criss-cross, and there are as many as 12 intersection points.
Can you imagine this beautiful picture?Just thinking about it makes my scalp tingle.
"I don't know who came up with the question. Isn't this intentional to kill the scumbags?" Qin Luo looked around and wailed everywhere.
Fortunately, although this question was difficult, it was acceptable to Qin Luo.
Three times, five times and two divisions solved the first problem.
When used, 5 minutes.
Then came the second question, algebra, which was not a problem for Qin Luo. In 3 minutes, the answer was already on the paper.
There is one last sequence worth 30 points left!
Looking around, Qin Luo smiled helplessly at the group of "weak students" who were battered and battered, the loneliness of a master.
However, in the next second, he froze in place.
This number sequence is very unusual!
证明：p＜2^（2^（n+1））时，Mp有2^（n+2）－n－2个是素数。
Emmmm!
This is completely a deformation of Zhou's conjecture!
He said whether to believe it or not, but he was quite honest in his heart.
Qin Luo can be sure that the person who produced this set of papers is Li Xueming.
In a sense, this is an exam specially prepared for him!
Breathing out the system warehouse, taking out the scroll, Qin Luo squeezed it down.
At this moment, the hall of learning opened a door for Qin Luo, and Zhou conjectured that theoretical knowledge rushed towards Qin Luo like a yellow river breaking its embankment.
-
In the monitoring room, through the cameras in the examination room, Li Xueming is monitoring Qin Luo's every move.
Zhou guessed that it was a question he added temporarily, and the purpose was very simple, he just wanted to sharpen Qin Luo's temper.
China has never been short of geniuses, but looking at the world, there are very few Chinese scientists who can achieve success in academia. One of the important reasons is that they are too arrogant and ambitious.
Qin Luo, the most outstanding mathematics genius of this generation in Beishan City, he didn't want Qin Luo to follow the old path of being oblivious to everyone.
Li Xueming smiled, Qin Luo's embarrassment of not being able to write had already been expected, "You are dumbfounded, boy, Zhou's conjecture is not so easy to prove."
"Leader, you are not afraid to scare him." A middle-aged judge said with a wry smile.
Originally, there were only two questions in the second test, and the last one was temporarily added by Li Xueming, just for Qin Luo.
"Jade can't be cut, it can't be used. Maybe he can become the second Zhou Haizhong in our Beishan City." Li Xueming said with a smile.
