    If A is a matrix of order \[2\times 3\] and B is a matrix of order \[3\times 5,\] then what is the order of matrix (AB)' or \[{{(AB)}^{T}}?\]

    Answer:

    Given, A is a matrix of order \[2\times 3\] and B is a matrix of order \[3\times 5,\] therefore the product AB is a matrix of order \[2\times 5.\] Then, the order of matrix (AB)' or \[{{(AB)}^{T}}\] is \[5\times 2.\]
