Are the following statements true or false? 1. If two row interchanges are made in sucession, then the determinant of the new matrix is equal to the determinant of the original matrix. 2. If det(A) is zero, then two rows or two columns are the same, or a row or a column is zero. 3. The determinant of A is the product of the diagonal entries in A. 4. det(AT)=(−1)det(A).
