Question

if a matrix of order 2 multiplied 3 and B is a matrix of order 3 multiplied 5 what is the order of matrix (AB) raised T

Answer 1

Step-by-step explanation:

The order of the product is the number of rows in the first matrix by the number of columns in the second matrix. ... Since the number of columns in the first matrix is equal to the number of rows in the second matrix, you can pair up entries.

Answer 2

Answer:

bro i can only give you hintωωωωω

Step-by-step explanation:

Since n~columns of B = n ~ rows of A, .’. BA exists. And the size of BA=mxp.. Then compute AB by multiplying the first row of B with the first column of A to get the first entry of BA , then the first row of B with the second column of A to get the second entry of BA, do this until the the you multiply the first row of B with the nth column of A. Then repeat all the same procedure until you multiply the nth row of B with the mth columns of A then you get your last entry of BA.
