二次根式的计算化简是初中数学的重要内容之一,下面通过六例总结了一些常用的二次根式的计算方法,熟练掌握这些方法可以使运算过程更简捷.1.公式法例1计算:(2~(1/2)+3~(1/2)-6~(1/2))·(2~(1/2)-3~(1/2)-6~(1/2)).
The calculation of the secondary root is one of the important contents of mathematics in junior high school. The following summarizes some commonly used methods of quadratic root by six examples, and proficiency in these methods can make the calculation process more simple.1 Calculation formula 1: (2 ~ (1/2) + 3 ~ (1/2) -6 ~ (1/2)) · (2 ~ (1/2) -3 ~ (1/2) -6 ~ (1/2) ).
