What is the minimum number of multiplications involved in computing the matrix product PQR? Matrix P has 4 rows and 2 columns, matrix Q has 2 rows and 4 columns, and matrix R has 4 rows and 1 column.

Let A be an m * n matrix and B an n * m matrix. It is given that determinant (Im + AB) = determinant (In + BA) where Ik is the k * k identity matrix. Using the above property, the determinant of the m
