Question
Which of the following is true for Matrix A that has 3 rows and 3 columns, Matrix B that has 3 rows and 3 columns?A. AB = BAB. A+B = B+ASelect an option Clear ResponseBoth A and BOnly AOnly BNone of the given options
Solution
The correct answer is "Both A and B".
Explanation:
A. AB = BA: This is not always true for matrices. The order of multiplication matters in matrices. So, AB is not necessarily equal to BA. However
