 Hi and welcome to the session. I am Deepika here. Let's discuss the question. Choose the correct answer. Let a be a square matrix of order 3 by 3 then determinant of k a is equal to a k into determinant of a b k square into determinant of a c k cube into determinant of a b 3 k into determinant of a. Let us write the solution. We know that if each element of a row or column of a determinant is multiplied by a constant k then its value gets multiplied by k. Since our given determinant is of order 3 by 3 so there are 3 rows or columns. So we have taken k as a common factor from each row or column therefore k a is equal to k cube into determinant of a because we know that for a square matrix a of order n determinant of k a is equal to k raise to power n into determinant of a. Hence the answer for the above question is c. I hope the question is clear to you. Bye and have a good day.
