If , then which of the following is undefined
Explanation for the correct option
Option(D): Order of a matrix is given by (number of rows)(number of columns) and the order of transpose of matrix is given as
(number of columns)(number of rows)
Given that
Two matrices can be added only if they are of same order
Matrices and can be added and
To perform matrix multiplication the number of columns of first matrix must be equal to number of rows of second matrix
Here number of columns of matrix i.e. number of rows of matrix i.e.
Hence, is undefined
Hence, option(D) is correct
Explanation for incorrect options
Option(A):
