解题过程中适时合理地运用分子与分母的有理化,往往会使解题更加简捷.本文略举几例,希望同学们能从中得到启示.例1化简(5 2~(1/2)+5~(1/2))/(2 5~(1/2)+2 2~(1/2)) The proper and rational use of the rationalization of numerator and denominator in the process of problem solving tends to make the problem more simple and easy.This article gives a few examples in the hope that students can get enlightenment from them.Example 1 simplification (52 ~ (1/2) + 5 ~ (1/2)) / (2 5 ~ (1/2) +2 2 ~ (1/2))
