Xueba, I beg you to go and escort him quickly!

The teachers also held their breath amidst the bursts of sighs.

"Hiss... hiss... thump!"

"!!!"

Then they just held back, not even daring to breathe.

Is it wrong?

They all think so, one by one you look at me, I look at you.

When Xu Heng picked up the pen again, the expressions of these teachers changed.

Xu Heng is a student after all!

After all, he is only a sophomore in high school!

Knowing how to solve a problem is already very rare...

after all……

But when they were comforting themselves, Xu Heng did not change his problem-solving process.

He just swiped and drew a horizontal line.

Separate the problem-solving process from the blank below.

Then, he started writing...

Let [r, s] represent the least common multiple of positive integers r and s, find the number of ordered ternary positive integer groups (a, b, c), where [a, b] = 1000, [b, c] = 2000, [c, a]=2000.

Only then did the teachers suddenly realize that Xu Heng had directly asked the other party a question!

This is really indecent!

Come on! ! !

What the hell!

FUCK FUCK!

Fuck, fuck, fuck!

These teachers almost cracked on the spot.

In the first reaction, some math teachers took out their mobile phones and searched for Xu Heng's questions.

Can't find it!

Can't find it at all!

How did he know this... this question?

A topic on a document?

still……?

"Could it be that he came up with the topic himself?"

Anyway, not online!

Anyway, all the math teachers present have never seen it!

They looked at me one by one, I shook my head, and then looked at you again.

Both of them were at a loss.

Everyone, "%￥#@￥￥......"

real or fake?

Not only do the questions in seconds!

You can also ask questions in seconds!

clap la la...

The three views of these teachers have been completely refreshed!

It’s okay if they’re not math teachers, those who are math teachers have their eyes wide open, their mouths open wide, and the wind is messy.

Xu Heng took another photo and sent it to Hong Jingjun.

These two people come and go back and forth to make friends by asking questions.

Hong Jingjun sent a haha-sized emoji, "NICE! Xu Heng! Thank you for your question!"

Xu Heng rolled his eyes, "Old Hong, you are going too far!"

Hong Jingjun, "I'm your fan too! I call you Xu Heng, you should be!"

puff-

The teachers almost vomited blood.

Their idol, the person they most wanted to be when they were young, turned out to be a fan of the high school student in front of them.

The idol of their idol turned out to be Xu Heng!

What made them even more astonished was that Xu Heng actually added another sentence, "Old Hong, do you want an answer?"

……

PS: Kneeling for support!There will be updates later! .

Chapter 296

Want an answer?

Teachers, "!!!"

Certainly not!

With Hong Lao's strength, do you need an answer?

Hong Jingjun also replied, "What do you think?"

Xu Heng, "Up to 3 minutes, after 3 minutes, I will send you the answer!"

On the side of the Hongjing army, there will be no more news from Xu Heng.

Because everyone knows that Hong Jingjun raced against time to do the questions after seeing the news!

Teachers, "!!!"

Xu Heng is too arrogant!

3 minutes?

It takes 3 minutes for Hongjingjun to give an answer.

It's not realistic...

Even if the Hongjing Army can do it, he can do it, besides the Hongjing Army, there is no other person!

and many more……

But in the next second, when these teachers thought that when Hong Jingjun gave Xu Heng a question, Xu Heng gave the answer directly without even a minute...

"KAO...!"

There is a teacher, the syllables of "reliable" popped out of his mouth...

He covered his mouth for an instant, and went out immediately.

"!!!"

The teachers were amazed!

The students were amazed!

Swish swish!

All looked at him.

He immediately apologized in a low voice, "I'm sorry, I'm sorry, I didn't mean it, you go on, you go on..."

Xue Laiyun had black lines on his face!

Continue your sister!

Can it continue?

Hissing for a while, leaning for a while, I think in a few minutes, you will start to "fuck, blah, blah, blah"!

Xue Laiyun, "%￥##￥￥%%￥%..."

He looked towards the last row.

Xu Heng raised his head at this time and looked at Xue Laiyun.

He actually saw pleading in Xue Laiyun's eyes.

Xu Heng frowned slightly, "???"

amount……

Class teacher, what do you mean by begging?

These teachers saw my chat records, I didn't say anything, I sacrificed myself so much, what else do you beg? !

Of course, Xu Heng was willing to show them this chat record.

Anyway, it's nothing to be ashamed of.

3 minutes passed quickly.

Xu Heng also wrote down the process of solving the problem:

解：显然，a、b、c都是形如2（m次方）·5（n次方）的数．设a＝2（m次方）1·5（n次方）1，b＝2（m次方）2·5（n次方）2，c＝2（m次方）3·5（n次方）3．

From [a, b]=1000=23·53, we know that max(m1, m2)=3, max(n1, n2)=3.

Similarly, max (m2, m3) = 4, max (n2, n3) = 3; max (m1, m3) = 4, max (n1, n3) = 3.

由此，知m3应是4，m1、m2中必有一是3．另一个可以是0、1、2或3之间任一种，因此m1、m2的取法有7种．

又，n1、n2、n3中必有两个是3，另一个可以是0、1、2或3．

因此n1、n2、n3取法有10种．故mi、ni（i＝1、2、3）不同取法共有7×10＝70种，即三元组共有70个.

Without any hesitation, Xu Heng sent it directly to the Hongjing Army.

And almost at the same time, Hong Jingjun also sent a message back to Xu Heng, "It's 70! My answer is correct, student Xu Heng?"

Xu Heng smiled, "That's right, I just gave you the process."

The teachers behind, "!!!"

It was really calculated by the Hongjing army!

Did not let them down!

Hong Jingjun, "Xu Heng, you almost killed me! If I were a few dozen years younger and I had a better brain, maybe it would be more than enough. Now..."

"Ah! That's not right. If it was decades ago, I'm afraid I wouldn't be able to do such a problem!"

"Hahaha!"

"I am an old man who is willing to bow down!"

Xu Heng, "%$#@$%..."

After ignoring Hong Jingjun's words, Xu Heng tilted his head on his arm and began to watch the drama by himself.

After watching the TV series, watch some recently updated anime.

What is the second season of Moe King, hey...it's not very good!Not as good as the first season!

Spider lady?

Reincarnation without a job?I'm going... Something's wrong with the plot!
