Multiplication of a matrix A with null matrix

Scalar matrix and identity matrix

Let matrix B be the adjoint of a square matrix A.I be the identity matrix of same order as A. If k(ne 0) is the determinant of the matrix A. then what is AB equal to ?

Multiplication of a matrix by a scalar and its properties

algebra OF matrix- addition || scalar multiplication || multiplication OF 2 matrix || properties OF multiplication

If an idempotent matrix is also skew symmetric then it can not be 1 an involutary matrix 2 an identity matrix 3 an orthogonal matrix 4 a null matrix.

Choose the correct answer If A,B are symmetric matrices of same order,then AB BA is a (A) Skew symmetric matrix (B) Symmetric matrix (C) Zero matrix (D) Identity matrix
