WebOnce it is in that form so that it appears like: Then the determinant = the product of the entries along the diagonal, such that determinant = (1) (2) (3) (3) = 18. Note* if the main diagonal contains a zero the determinant is also 0, thus the matrix is not invertible. Hope that was clear enough to help. WebSince it has three rows and three columns, we call it a 3 x 3 matrix. Since the number of columns and rows are equal, this is a square matrix - which means that it will have a …
