If two rows and columns are identical then determinant isQuestion 8Answera.1b.0c.Identity matrixd.-1

If two rows/columns are identical then the determinant isQuestion 9Answera.1b.1/2c.-1d.Zero

Suppose that A and B are n×n matrices. Check the true statements below: A. If det(A) is zero, then two rows or two columns are the same, or a row or a column is zero.B. det(AT)=(−1)det(A)C. If two row interchanges are made in sucession, then the determinant of the new matrix is equal to the determinant of the original matrix.D. The determinant of A is the product of the diagonal entries in A

Which of the following is/ are TRUE?Determinant evaluated across any row or column is same.Determinant of a Identity matrix () is 1.If all the elements of a row (or column) are zeros, then the value of the determinant is zero.a.1 and 3 onlyb.3 onlyc.All of the aboved.None

f two rows of any square matrix are identical, then the value of determinant is:2−11

Identity matrix is always:
