Question

the order of matrix A us 3×5 and the order of matrix B is 5×2 then the order of product AB is​

Answer 1

Answer:

2×5

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
