If A and B matrices are of same order and A + B = B + A, this law is known as
If A is a non singular matrix of order 3 , then adj(A^{3}) =
If A and B are any 2 × 2 matrices , then det. (A+B) = 0 implies
If I_{3} is the identity matrix of order 3 , then 1_{3}^{−1} is
If A and B are square matrices of same order and A’ denotes the transpose of A , then
If the entries in a 3 x 3 determinant are either 0 or 1 , then the greatest value of this determinant is :
In a third order determinant, each element of the first column consists of sum of two terms, each element of the second column consists of sum of three terms and each element of the third column consists of sum of four terms. Then it can be decomposed into n determinants, where n has value
