"Knowing the positive numbers a, b, c, and satisfy: 5b-3c is less than or equal to b less than or equal to 4c-a, and at the same time, clnb is greater than or equal to a+clnc, find the value range of b/a!?"

Looking at the question that appeared in front of his eyes, it didn't seem to be very long, but in fact, it contained a lot of information, and a touch of sadness appeared on Zhou Dashao's face, he knew that this should be a former college entrance examination question, because, just last night, he found this question from a top-secret test paper question bank.

It seems to be the so-called inequality solution, but in fact, it is basically impossible to use the inequality to find the answer, perhaps, some people can think of it, using techniques such as scaling, to deal with it, but that method, it is also impossible to solve it.

This is a comprehensive knowledge of inequalities, functional relations, and linear programming, and the scope of its investigation has far exceeded the scope of what they have learned today, in other words, this is a problem for guarding, not for people to do, because this is a problem used to deduct points.

So, what if you made it!?

Hey!!

After showing a meaningful smile on his face, Zhou Dashao directly filled in the answer and immediately started the next question.

At this moment, many math masters, including Chen Xiao, have spent nearly ten minutes and still haven't dealt with the 14 fill-in-the-blank questions, and they have also started the next questions.

In the final analysis, this test paper, starting from 11 questions, has begun to set up obstacles everywhere, and it has become a super difficult thing to break through the defense and then achieve extremely high scores, among them, Chen Xiao secretly said that he was lucky, saying that in addition to 14 questions, there are not many remaining problems.

The two-day exam started quickly and ended just as quickly.

Of course, there is still a period of time before the results are released, and after the exam, what makes many people feel speechless is that the teachers who have been waiting for a long time have also started the bombardment of various subjects.

All kinds of test papers, like snowflakes, fell on every desk, and in a large wail, it was the beginning and end of the practice again and again, in this process, Zhou Xuan, instead, felt a faint fulfillment.

In the blink of an eye, another week passed.

In the past week, the editor-in-chief from [Dingjian Pavilion] also appeared in Jiangcheng, and signed a new contract with the editor-in-charge Ding Xiangmei, who had a relationship with Zhou Dashao.

Regarding the plot development of [Breaking the Sky], the two sides have also entered a new round of negotiations, after all, Zhou Dashao has already considered the so-called game adaptation in advance, as well as physical publishing, and even, adaptation into a movie, etc., such things are no stranger to him who was reborn.

So, after [Breaking the Sky] occupied the first place in the monthly pass several times in a row, the contract between the two parties also ended simply and without any suspense.

Morning!

"It's recess exercise again, this kind of, I don't know when, it's the head, anyway, when I was a freshman in high school, in order to practice this recess exercise, many of my brother's homework were referenced at the same table."

"Hehe, is that why you're in a parallel class now?"

“......”

On the playground, there have been dense students of different classes, naturally, including different grades, with the sound of gymnastic music, everyone has begun to do morning exercises, some restless students, is in the arrest of the student union comrades, successfully appeared in the front row.

Of course, in such a scene, the homeroom teacher will appear in it, from time to time, from his own class, find a few indiscriminate boys, pull them out, or use the right time to have a good talk with them to avoid revealing their stuffing.

"Well, sure enough, it's very youthful!!"

Due to his height, Zhou Dashao stood in the last few rows, looking at some of the student union boys who were standing with paper and pencils, he was also very serious about doing different beats and various movements.

"You guys, learn more from Zhou Xuan!!"

Another beat passed, and the head teacher Ye Qingmei also came to the last row, and after a careful observation, he said to some of the boys who appeared in the back row, to be honest, I don't know why, although Zhou Xuan didn't have any special performance, she always felt that this teenager was not simple.

This must be a teenager with a story, of course, from the first year of high school, Zhou Xuan's fame in the first year of high school, she also knows that this kid has been rejected by a girl in an art class nearly a dozen times, and he is still persevering, and his grades are extremely good, which seems a little bizarre.

Generally speaking, students who fall in love in high school will not have very good grades, but this kid has changed this tradition!

"Hmm, got it!!"

"Teacher Ye's criticism is good, we all know it!"

“......”

In the afternoon, between classes.

Due to the relationship of the college entrance examination, there will be 1 listening training at noon, of course, the broadcast in the classroom, and each student has their own listening book in their hands, such a thing has basically become a compulsory course, in the previous life Zhou Dashao often used a knife and gun directly with foreigners, and sometimes, there would be a war of words.

This also leads to the fact that his English level has also maintained a relatively good level, of course, this level, compared with Chen Xiao, Ye Rou, Ye Lian'er and the like, there is still a big distance, this is talent.

"Hmm, Ben Shao wrote all the choices before the first paragraph of listening, so will he be scolded!?"

With a hint of anxiety, Zhou Dashao, who was sitting in the back row, quickly slipped to the toilet in the time when everyone was answering, and after dealing with his own affairs, he whistled and was about to return to the classroom, but he was stopped by a girl wearing a blue and white school uniform.

"Hello, do we know each other?!"

He seems to have face blindness, or maybe he said it on purpose.

"Of course I know, my name is Qi Wanru, a few days ago, you saved me? What, this was forgotten!? ”

A wicked smile appeared on the girl's face, and immediately, she approached Zhou Xuan directly, and whispered in her ear: "You touched my whole body, do you want to run away after taking advantage!?" ”
