一、怎样估计生活中的数据方法1:通过简单的数学计算来估计．方法2:与同类较熟悉的事物做比较来估计．例1 假设有一张足够大、厚度为0．05 mm的白纸,请全班50名同学轮流对折1次,请你估计一下折叠后的厚度是否会达到100万km．解析:一个班50名同学,每对折1次,白纸的层数都增至对折前白纸层数的2倍,轮流对折后,白纸就有
First, how to estimate the data in life Method 1: Estimate by simple mathematical calculations. Method 2: Compare with similar familiar things to estimate. Example 1 Assume that there is a large enough paper with a thickness of 0.05 mm. Please ask 50 students in the entire class to fold in turns. Please estimate whether the folded thickness will reach 1 million km. Analysis: A class of 50 students, each fold 1, the number of white paper layers are increased to two fold before the white paper layer, after the turn of the folded, there is a white paper
