When I was a guest at my girlfriend’s house, her dad took out the Desert Eagle

Look at the numbers on the calculator.

Lin Xuerou was a little blind.

Shearwater's eyes looked at her boyfriend with confusion.

She couldn't believe that her boyfriend could really calculate such a complex problem.

After all, this is far beyond what ordinary people can calculate.

Kong Xuan naturally also noticed his girlfriend's gaze.

He quietly approached Lin Xuerou's ear.

He whispered, "Please call me a genius." "

Then he was caught off guard and secretly kissed her on the ear.

Lin Xuerou's eyes widened sharply.

His face was like an autumn sunset.

Instantly red and transparent.

Kong Xuan only thought that she was shy in front of her family.

I still have doubts in my heart.

She doesn't blush so easily on weekdays.

And ......

This red is too exaggerated!

How did he know.

Lin Xuerou is actually shy in front of the people of the whole country!

See this scene.

Netizens couldn't hold back.

- "Hahahahaha

- "The heroine is so cute!".

- "The main character is so cute!".

- "Something is wrong upstairs. "

- "Made! you can be stuffed with a mouthful of dog food when you watch a variety show!".

- "Hahahahaha, the protagonist actually steals the heroine, it's so funny, hahahahaha, ah, ah, I'm so angry that I ......

woo ".

——“......"

Xu Zihan's quick answer.

And it didn't come as a surprise to anyone.

Of course.

Except for Kong Xuan.

After all, it is a well-deserved champion of the intelligence talent show.

Don't say you can't answer this kind of question.

Even if she answers slowly, she loses.

Next.

It was Xu Zihan's turn to ask the question.

Everyone stared at the screen expectantly.

I really want to know what questions Xu Zihan will ask to embarrass Kong Xuan.

Behold.

Xu Zihan suddenly raised the corners of his mouth.

Said to Kong Xuan:

"Otherwise. "

"Let's change the algorithm. "

"What algorithm?" Kong Xuan asked.

"Open root number. "

"Open root number?".

"Are you afraid?"

Kong Xuan sighed.

Prepare to tease her.

"What a joke!".

"Do you know what people call me when I was in school?".

Xu Zihan thought about it seriously.

Then he shook his head.

Kong Xuan raised his eyebrows:

"They all call me. "

"Prince Nemachi!".

Poof!

In the studio.

Luo Wan'er didn't hold back again.

The music sounded.

Xu Zihan also reacted.

This guy is definitely teasing himself.

I don't talk to him about it.

Rolled his eyes.

Start the question directly on the manuscript paper.

【√999】

That is, to find the square root of 999.

Ordinary people are no strangers to open root numbers.

I

learned it all in middle school.

But it also shows some simple root numbers.

Numbers like 999.

It's not enough to open at all.

You can only get an approximate value with a calculator.

Not to mention mental arithmetic.

If it is said.

Just to the nearest decimal place.

Maybe you can still be blinded.

But the more exactly it is after the decimal point.

The higher the difficulty.

And when Kong Xuan asked this question.

Xu Zihan's request is even more outrageous.

"How many digits are exact?"

"Uh-huh......

".

"It's the same as before. "

"Accurate to thirteen decimal places!".

Hear this request.

Kong Xuan was directly stunned.

He asked again, a little uncertainly

"Thirteen decimal places?".

"Are you sure?".

Xu Zihan nodded indifferently.

"I'm sure. "

Kong Xuan finally showed a rather surprised expression.

He looked the little girl up and down.

Exclaimed: "Do you know what that means?".

The little girl nodded again.

Kong Xuan finally began to pay attention to the immature-looking little kid in front of him.

Netizens were a little confused by his questioning.

- "What do you mean, why didn't I understand?".

- "Is there a math guru to explain the explanation?".

- "To put it simply, if you are accurate to thirteen decimal places, it is not simply a matter of opening the square root of a three-digit number. "

- "What's the problem then?".

- "That's equivalent to giving a square root to a 29-bit number." "

- "I'm going!29 digits?really?".

- "As a PhD student majoring in mathematics, I can be sure that what is being said upstairs is true. "

- "Damn! If this can be calculated, can I apply for the Guinness Book of Records?"

- "Well, it's hard, but it's still far from the world record. "

- "That's right, I remember the world record for the open root, it was a foreign guy who opened a 200-digit number to the 13th power!, and it only took 77 seconds!".

- "Nima! Two hundred?".

- "I have to watch it for a long time, and people can think of the answer in 77 seconds?".

- "We don't understand ...... in the world of great gods."

Kong Xuan at this time.

No world records were taken into account.

He looked at the title on the paper.

Fell into a brief contemplation.

Accurate to thirteen decimal places.

This is equivalent to adding 26 zeros to the end of 999 on the question.

That is, to find the square root of a 29-digit number.

If you open the root number directly.

Kong Xuan could also quickly think of the answer.

But he wanted a universal matrix formula.

Not only can you find the 29-digit square root.

You can even find the 290th root of 290 digits.

So he closed his eyes.

Begin to fully mobilize the "math" skills at the full level.

It's like there's a storm going on in my head.

Countless mathematical symbols in the sea of knowledge are flying wildly.

Minutes and seconds passed.

Soon only the last bit of sand in the hourglass remained.

Xu Zihan on the side.

Look at him meditating.

I couldn't help but curl the corners of my mouth.

Look at the time is almost up.

She also gave a friendly reminder.

"Hey, time is running out. "

Kong Xuan's eyes opened suddenly.

Sure enough, I saw that the sand in the hourglass was almost gone.

So he quickly picked up the pen.

A series of numbers were written on a piece of paper.

【31.**2】

After writing.

He closed his eyes again.

It seems that he is still trying to think about something.

And look at the string of numbers.

In the hall of the villa at this time.

Everyone was silent.
