1. The problem statement, all variables and given/known data

show that det(A)=(detA)*= det(A$) where * denotes complex conjugate and$ means transpose

2. Relevant equations

3. The attempt at a solution

Please help me to start the problem.I am not getting a way.

You are posting problems faster than you are solving them. The first half of your equality is simply not true unless det(A) is real. Please reconsider.

The proof of det(A^T) = det(A) (at least the one I know about) is about using the definition of the determinant and the properties of permutations.

Further on, I'm not sure what you mean with det(A)=(detA)*.
