学习平方差公式时,遇到这样一道题: 题1 计算: (1+1/2)(1+1/22)(1+1/24)(1+1/28)．这题架式不大,却也挺吓人．仔细观察,发现各因式的结构是有规律的,它让我想起了另外一道题的解法:
When learning the squared difference formula, we encountered such a problem: Problem 1 Calculation: (1+1/2)(1+1/22)(1+1/24)(1+1/28). This type of question is not large, but it is also scary. After careful observation, we found that the structure of each factor is regular. It reminds me of the solution to another problem:
