complex conjugate of a+bi is a-bi

The Attempt at a Solution

I defined M = A+Bi, where A and B contain real number entries. So that means that \bar{}M = A-Bi. Past that point, I don't know what to do. How can I find the determinant of the conjugate matrix? Or the complex conjugate of det (M)? Could someone give me a hand?

I'd say that the determinant of a matrix is a bunch of additions on products of complex numbers which make up the matrix.

Note that when you multiply or add 2 conjugate numbers, the result is the same when you multiply or add the original numbers and then take the conjugate.

So the determinant of a conjugated matrix has to be the same as the conjugate of the determinant of a matrix.

I think using induction and then doing a cofactor expansion would work, though I haven't checked the details.
