If a matrix B is obtained from a square matrix A by interchanging any two of its rows, then what is |A+B| equal to

True or False : Let A be a square matrix of order nge2 and B be the matrix obtained from A by interchanging two of its rows then det B = det A.

For any square matrix A,A A^(T) is a

If the matrix B is the adjoint of the square matrix A and alpha is the value of the determinant of A, then what is AB equal to ?

For any square matrix A,(A-A') is :

Let |A| = k. If B is the matrix obtained by interchanging two rows of A, then |B| = ?

If A is any square matrix then A + A' is a :

Let A be a square matrix of order n(>=2) and let B be a matrix obtained from A by interchanging any two rows (columns) of A ; |B|=-|A|

If A is any square matrix, then
