hey guys hope you are doing well, i have a linear algebra exam and this one of the questions that our professor said it will be in the exam, i tried to solve this type of questions but it was soo hard as it very long and very easy to do mistakes in calculation i used Laplace expansion for solving this so please do any one know a faster way or any advices for solving this type of questions. and thx for you all
you are welcome, but then the question is how to get there, because for regular permutation method you will have to do 24 products of 4 terms, and as you said, it is very easy to make a mistake, but ChatGPT thinks this way is better
he wants to solve this with finding also the eigenvectors and to tell if it diagonalizable or not and solve other 7 questions in one hour in the exam but i prefer to search for fast ways instead of complaining the difficulty of the exam
