Indian talented girl, threatening that mental arithmetic is faster than computer 10 second. What did Hua say?

Remember a movie many years ago? A talented girl helps her classmates pass the exam and get money with her IQ. Genius is beyond the reach of many people, who are born to master knowledge and skills faster than ordinary people in some fields. If their technology and knowledge can be used in the right place, it will bring a lot of progress to the country and even society. Today's heroes are also geniuses.

This genius is from India, and her name is Shakuntala. Her genius lies in mathematical mental arithmetic. This gifted Indian girl can do mental arithmetic much faster than the computer, claiming that the mental arithmetic speed is faster than the computer 10 second. To know that the computing speed of a computer is calculated at the speed of light, it can be seen that the mental arithmetic speed of this talented girl can be said to be very fast. But in a competition, Hua: The calculation was wrong. Why does Hua, as a leading figure in our mathematics field, say that this talented girl has miscalculated? Isn't this talented girl really that talented? What the hell is going on here?

Shakuntala was born in a very simple family in India. Besides her parents, she has a brother. Their livelihood depends entirely on their parents' performances in the circus. Therefore, Shakuntala grew up in a circus and never received any systematic and formal education. But gold is everywhere.

Shakuntala's cleverness comes from a very difficult math problem of his brother. That day, Shakuntala's brother was doing a three-digit open question to test his computing ability. Just as his brother was trying to calculate, Shakuntala, who happened to be playing nearby, glanced at the topic and told him that I knew the answer to this question. Brother naturally doesn't believe it, because Shakuntala has never been exposed to mathematics, so it is impossible to know the answer. In order to convince his brother that he knew the answer, Shakuntala and his brother had a competition to see who worked out the answer first.

The result of this game is of course Shakuntala's victory. He is faster than his brother who studies mathematics. The result surprised the whole family. In order to verify Shakuntala's mental arithmetic ability, her parents took her to many calculation competitions, which fully verified Shakuntala's genius. Since then, Shakuntala has become more and more famous as a genius, and more and more people have challenged her. Someone even challenged her with a computer, but these challengers all failed in the end, and the computer also lost to Shakuntala.

This stop has made people all over the world know the name Shakuntala, but the number of challengers has not decreased. 1982, an American professor challenged Shakuntala. At that time, "Univac 1 180 electronic computer" was used to participate in the competition, which was an excellent computer model in the United States at that time. The challenge this time is to calculate the 23rd root of 20 1 bit. This topic may be beyond understanding just by looking at it, let alone calculating it. But within 50 seconds, Shakuntala worked out the answer. The computer takes more computing time 10 second than Shakuntala. So will Shakuntala win this challenge again?

After reading Shakuntala's answer, our math master Hua said: You have miscalculated. Because in mathematical rules, any square root and the tail of the root are integers. So the number 10 in the answer given by Shakuntala is wrong. Although this mistake was recognized a long time later. No one pointed out her mistakes in the game at that time. She is still that talented mental arithmetic girl. However, after that, there were few reports about Shah Kintala. This gifted girl is only a fortune teller now, which makes people sigh.
