| 摘 要： | 在复数开方运算中,学生易犯的错误是把实数开方运算中的一些运算法则直接搬过来运用,错了还很难发现问题所在。就实际教学中出现的几个复数开方运算问题为例说明问题所在,避免学生今后再犯此类错误。

| Abstract: | In the complex root operation,students easily made a mistake by using some algorithms in the real root operation to the complex root operation directly.This paper will illustrate the reasons of the mistake through several problems in the actual teaching,in order to avoid the similar mistakes in the future by the students. |
