Answer 2

Answer:

Rank of a square matrix A of order n is always less than or equal n . In case, if the matrix A is non-singular that is det(A) ≉ 0 , then A itself is the highest order minor having non-zero determinant . Therefore, rank of A = n . This is true for all square matrices of order n, not just non-singular matrices.
