To find: Whether the matrix product is defined and also state the dimension for the product of

Answer to Problem 26PPS
The matrix product is defined and the dimension of
Explanation of Solution
Given:
The expression is
Calculation:
The first matrix is of the order
The product of two matrices is defined as the number of columns of the first matrix is equal to the number of rows of the second matrix.
The order of matrices
Therefore, the product is defined and dimension is
Multiply the matrices to obtain the product:
Thus, the matrix product is defined and the dimension of
