底数不同的两个对数值大小的比较,一向是中学数学的难题,应用放缩法和加倍法原理是可以解决这类问题的 1 放缩法 定理 设b>a>1 当N>1时,则 log_aN>log_bN 当Oa>1 所以
The comparison of two logarithmic values with different base numbers has always been a difficult problem in middle school mathematics. The principle of scaling-down and double-doubling is a scaling theorem that can solve such problems. Let b> a> 1 When N> 1, Log_aN> log_bN When O a> 1
