A simple plural problem Find all solutions of Z ^ 7-1 = 0 What is 1? I tell you it's | Z | Is | Z | = 1, z = 1? The one on the fourth floor is a little reliable, but it's wrong. Because if n can take any number, then it will definitely have more than seven roots, but whether it is a complex number or not, it can only have seven roots at most, so you can judge that you are wrong without looking at how you solve it. Even if you can draw infinite solutions in the complex plane, it is not infinite, it is just repetition.
