The group pet sister fell off again

Chapter 171 The math competition begins.

"Dear audience, we meet again! Today is the second day of the national cultural exchange meeting, yesterday's competition champion is the Z national team, today our competition topic is mathematics, after all today's champion flower falls who?
Let us look forward to it.
Today's rules are the same as yesterday's. Let's ask the representatives to decide the order of the game for the draw." (Dear audience friends, we meet again! Today is the second day of the National Cultural Exchange Conference, yesterday's game The champion is the representative team of country Z. The topic of our competition today is mathematics. Who will be the champion today?
Let's stay tuned.

Today's game rules are the same as yesterday, so let's invite representatives to draw lots to decide the order of the game. )
It was still the same as yesterday, the representatives of the elder group were all on stage.

The representative sent by Country Z is Mr. Quan, and the representative sent by Country M is Si Qiqi's teacher, Ma Chabesi.

Everyone else is still the same as yesterday.

Quan Moxie looked at old man Quan from the audience, and always felt that old man Quan looked familiar, but he was a little strange.

Quan Moxie couldn't explain this feeling, but in the dark, he always felt that this old man would not hurt him.

Quan Moxie didn't know how this feeling came about, so he could only suppress the doubts in his heart, and planned to go back to ask Quan Jiuli what was going on at night, this old man participated in the competition with Quan Jiuli, maybe she should know What is the matter with this uncomfortable feeling in my heart?

The result of the lottery came out, country Z played against country F, country M played against country C, and country Y played against country R.

Country Z sent the first brother Zhang Jiaming, the only twin brother among the participating team members.

And Zhang Jiaming was fighting against a man with dyed red hair.

“Since this competition is an academic competition, this competition takes the form of two wins in three games. The two sides decide the winner of the first game in the form of the most traditional rock, paper, scissors, and then the party that loses the stone. It is in the second game. If there is a one-to-one draw, the last game will be officially presented. Note that in this game, everyone can only play once. If they play in the middle, they must change to another representative.
Next, let's get the game on!" (Because this competition is an academic competition, this competition will take the form of two out of three games. The two sides will decide to be in the first game in the most traditional form of rock-paper-scissors. The person who sets the question, and then the loser of rock-paper-scissors will set the question in the second game. If there is a one-to-one draw, the official will make the question in the last game. Note that in this game, everyone You can only play once, if you play halfway, you must change another representative to come on stage.

Next, let's race, let's start! )
The scene changed, and they came to the venue for the competition between country Z and country F. There were four large white boards on the field, while the red-haired man and Zhang Jiaming stood opposite each other.

"Hello, I am Zhang Jiaming, please give me more advice." (Hello, I am Zhang Jiaming, please give me more advice.)
"Hello, this is lake. Please give me some advice." (Hello, I'm Lake, please give me some advice.)
The two started rock-paper-scissors. To be honest, at this moment, in this place, it was a bit shameful to come to rock-paper-scissors.

Somewhat unexpectedly, Zhang Jiaming lost, Lake won the first bat, and Lake wrote the topic on the official whiteboard.

The topic is relatively simple compared to their academic masters:
After the point A (-√2, 0), the moving circle of B (√2, 0) intersects the Y axis at M. N two points, C (-1, 0), D (1, 0) are two points on the X axis, the straight line MC and ND intersect at P.Find the equation of the locus E of the point P. √ represents the square root of 2.Knowing the number sequence An: An=n+1+8/7An+1, and there is an integer K greater than 1 so that Ak=0, m=1+8/7A1. (1) Use K to represent m (into the most commutative formula) (2) If m is a positive integer, find the 3 of k and m.If the real coefficient equation x2+ax+b=0 about X has two roots, one root is in the interval (0, 1) and the other is in the interval (1, 3), the point (a, b) corresponds to The region is S.Assuming Z=2a-b, find the straightening range of Z. (The topic was found on the Internet, but the author can’t understand it either.)
Zhang Jiaming looked at this question, thought for a few minutes, looked at Lake a little speechlessly and said: "Dude, you have the nerve to ask that question?" (Brother, are you willing to ask that question?)
"Don't look down on it. If you don't answer it soon, you won't be able to answer the victory of the first game. Our F country will take it.)" , If we can’t answer the victory of the first game, our country F will accept it.)
"Who says I can't answer it? Watch it." (Who says I can't answer it, watch it.)
As he spoke, Zhang Jiaming quickly wrote the answer on his whiteboard.

Watching Lake gradually show a surprised smile, Zhang Jiaming's smile deepened.

The champion of this game, he is sure.

　From this one on, I started to briefly write about the content of the other contestants, paying attention to the contest between the heroine, the fifth brother, and Si Qiqi.
