在兴趣课上,老师介绍了勾股定理(西方称毕达哥拉斯定理)后,写出了四条等式:32+42=52;52+122=132;72+242=252;92+402=412,要求我们观察并记住这几个比较特殊且有用的式子.我在观察式子时不经意间有了两条发现:1.等式中和的底数比第二个加数的底数多1;2.等式中第一列加数的底数是
In the interest class, the teacher introduced the Pythagorean Theorem (Western called Pythagoras Theorem) and wrote four equations: 32+42=52; 52+122=132; 72+242=252; 92+ 402=412, asking us to observe and memorize these more special and useful formulas. I have inadvertently discovered two things when looking at an equation: 1. The base of the sum in the equation is greater than that of the second addendum. The base number is 1; 2. The base of the first column addend in the equation is
