The group pet boss is a living ancestor

Chapter 86 Song Li writes the answer directly
This is Song Li's first time attending school. If she had to say a word about her experience in class, it would be: sleepy.

Due to the special nature of this exam, teachers also pay special attention to it, and there is no way to make up for the content of professional courses all at once.

However, the two items of advanced mathematics and English can indeed be supplemented by guessing questions temporarily.

Although Song Li is not very interested in learning this kind of thing, she has lived such an old age, and collecting things and maxing out various skills has always been her only hobby.

Well, it's not the only one anymore though.

But the knowledge level of the exam is too shallow, for her, she can write the answers casually.

The high mathematics teacher was excitedly explaining the possible exam questions on the podium, and each of the students below seemed to be so focused and serious.

"Let's invite a classmate to come up to the stage and do this question." The teacher glanced at the whole class, and finally set his sights on Song Li who was in the corner: "That classmate in the fourth group sitting in the farthest corner, come up and answer the question." .”

According to Song Li's hearing ability, she was able to hear the teacher's words clearly even when she was looking out the window with headphones on.

In the next second, everyone's eyes fell on Song Li.

I saw her eyebrows move slightly, took off her earphones, and slowly got up.

The moment she got up, Song Shuwan raised her hand and then stood up: "Mr. Zhang, that my sister hasn't come to school for a year, and she has missed a lot of lessons. Let me answer for her."

"Nonsense!" Teacher Zhang pushed up the gold-rimmed glasses and looked at Song Li: "I need someone else to answer the questions, so don't I need someone else to take the exam?"

Song Shuwan was told a lot, her eyes pretended to be aggrieved.

Everyone's eyes also fell on her, casting friendly glances at her.

Being so considerate and repaying hatred with kindness, she is really a very kind girl in the eyes of her classmates.

Song Li hummed softly, put her hands in her pockets, and walked towards the podium.

Seeing this, Song Shuwan drew a faint smile on the corner of her mouth.

In fact, she knew that Song Li would definitely not accept her kindness. These words could help her establish a good image in the class and watch the excitement, so why not do it?
This is a difficult advanced mathematics problem. The title is: Find the extreme value of the function z=3axy-x^3-y^3 (a>0).

Many students also picked up pens to analyze and calculate. The moment Song Li stood on the podium and picked up the chalk, he heard someone gossip.

One of the people who participated in the discussion was Liang Bi who made a bet with her to become a bully.

"This question doesn't look easy, can Song Li do it?"

"I think it's a bit difficult. I think it will take a long time to think about it. I don't even have an idea yet."

Liang Bi heard the conversation between the two people behind her, and turned her head, the decibels were a bit louder.

"Aren't you two funny? She can do this kind of problem? You have to be smart when you talk. She used to be so poor in her studies, and her current level is probably at the stage of ninety-nine multiplication tables."

Song Li stood on the podium, glanced at the question, without the slightest hesitation, directly picked up the chalk and wrote down the answer.

There is a maximum value Zmax=a^3 at (a, a).

The process of this question was a bit cumbersome, and Song Li was too lazy to write, so she put down the chalk after writing the answer, turned around, walked off the podium and walked towards her seat.

Because she wrote the answers so fast, she hardly thought about it, as if she was answering 1+1=2.
