We are given with two invertible matrices A and B, how to prove that
?
We know that if A.B
then it means B is inverse of matrix A where
is an identity matrix.

How to prove that adjoint(AB)= adjoint(B).adjoint(A) if its given that A and B are two square and invertible matrices.
Using formula to calculate inverse of matrix, we can say that
(1)
adj(AB) is adjoint of (AB) and det(AB) is determinant of (AB).
(2)

Note: This property holds for square matrices.
If, we are given matrix A then
