在学习到二次根式时,我们会发现二次根式中有很多很有趣的规律,现在我们将这些规律进行归纳,并给以必要的证明,以便于学生能够更系统的进行学习,更进一步的激发他们深入探讨的兴趣.一、下面我们就来共同欣赏一下这些规律引例观察下列各式及验证过程:
As we learn about the second root, we find that there are many interesting rules in the quadratic root. Now we summarize these rules and give necessary proofs so that students can learn more systematically. Further Stimulate their interest to explore in depth.First, here we come together to appreciate these rules cited the following examples and verify the process:
