Question

Du A and B que matuíce of_order 5X2 and
3x5 suspechvely, what the order of
(BA)'​

Answer 1

Answer:

Step-by-step explanation:

Theory:  Two matrices are said to be conformable for multiplication if the number of columns in prefactor is equal to the number of rows in the post factor. The order of the resultant matrix is the number of rows in prefactor matrix times the number of columns in the post factor matrix

i.e., if A=[aij​]n×m​ and B=[bjk​]p×n​

Then, multiplication of the matrices [B]p×n​×[A]n×m​ results in matrix [BA]p×m​.

Given, [A]3×5​ and [B]2×3​

Hence, order of the matix [BA] is 2×5
