As Shi Ning and Lu Shi'an, the two universities, in class, even Teacher Ding dared to interrupt casually in the whole classroom, for fear that he would interrupt like this, so he inquired about the two of them to find out the wonderful questions.

"Your way of thinking, the answer is definitely 14, 60. From the conditions, we can see..." Shi Ning stood on the podium, holding chalk in his hand and writing quickly on the blackboard, "and a1

b10…Repeat the recursive relationship of {am} to know…”

This is a league question, which is very difficult. Shi Ning wrote while talking. In a short while, the two blackboards were filled with them. "...get the only positive integer... Comprehensively, why are all possible for a1b1 14, 60, absolutely impossible to be 13, 60, Lu Baoan, you are at this step..."

Shi Ning took the chalk and stroked it hard under the verification on the second blackboard, "You can forget it here, there is no solution here. If you don't believe it, you can calculate it yourself."

The greatest joy of mathematics lies in "verification". In the process of verification, it is like a fish swimming in a river, rushing happily and tirelessly, and only feels that they are flying. The more difficult it is, the more they want to conquer. Once the conquest is successful, the great sense of accomplishment you have gained will be a joy of stepping on the clouds and floating.

Shi Ning likes this feeling very much, and also likes the duel with Lu Shian and Xi Qinghuan, so happy that he looks forward to the next duel.

The students under the podium followed Shi Ning's idea and calculated it. Damn, it seems that Shi Ning's idea is correct, but Lu Shi'an's idea is correct and the answer is correct.

Then who is right and who is wrong?

Teacher Ding looked at the corners of his mouth slightly tightened, his eyes tightened, and his eyes locked the board. Then he looked at Shi Ning, who was full of confidence. Teacher Ding, who had a smile on his face, spoke up, breaking the tense atmosphere in the classroom, "Xi Qinghuan, what about you, what is your answer."

Xi Qinghuan glanced at his answer, Qing Lingling's peach blossom eyes looked at Shi Ning, and said indifferently: "13,60."

"Wrong, 14, 60." Shi Ning smiled, and the chalk was drawn under the analysis process of the third black report, "You must be a problem here."

Xi Qinghuan didn't even read his answer book. When Teacher Ding and his classmates were watching, he nodded slowly. Yes, he was the difference between Shi Ning's place and Shi Ning.

"The only positive number obtained here is a1=18, and at this time a1b1=20, not 60." Shi Ning's gaze looked at the silent Lu Shian for a moment, and the corner of his mouth curled up slightly, "Student Lu, am I right?"

Lu Shian had already read all the analysis of Shi Ning, and he quickly analyzed it in his heart. When Shi Ning asked him, it was the time when he thought about it.

Hearing this, he smiled and said, "Well, I was wrong with this question. It was indeed 14, 60, you won." This was the third time he lost in Shi Ning.

Shi Ning put down the chalk, patted the dust stained, and said with a smile: "Next time, I will continue to beat you."

"Let's wait and see." Lu Shi'an happily responded to the battle. Shi Ning liked this kind of matchup between chess and opponents. Similarly, Lu Shi'an also liked it very much. The pleasure of competing with the masters on the top of the mountains will make you see further and know that there is a heaven beyond the sky and there are people outside of the world. You can make yourself more cautious and not be complacent.

The two of them stopped fighting, and the students below all felt a sense of microseconds of successfully passing the tribulation together. Some students also had a "sadness" happening. Before they could figure out their ideas, the God of Learning had already solved the problem thoroughly.

Gap, this is the gap!

The Academy of Sciences received a postal package from Southern Province, which was mailed to Mr. Le. He felt something like a document when he touched his hand.
