Question

For a square matrix A and a non singular matrix B of the same other,the value offer( B inverse AB)​

Answer 1

Explanation:

det(B

−1

AB)=?

Where A is a square matrix.

and B is non-singular matrix, so B is invertible and a square matrix.

det(B

−1

AB)

=det(B

−1

BA)

=det(I

n

A) ( where I

n

is an identity matrix of order n )

=det(A)
