Question
Suppose P and Q are two different matrices of order 3 × n and n × p , thenthe order of the matrix P × Q is?
Solution
The order of the matrix resulting from the multiplication of P and Q will be 3 × p. This is because when two matrices are multiplied, the number of rows in the resulting matrix comes from the first matrix (P in this case) and the number of columns comes from the second matrix (Q in this case). So, since P is of order 3 × n and Q is of order n × p, the resulting matrix will be of order 3 × p.
