Need help with a quantum chemistry problem

In summary, the person is struggling with a problem and is seeking help from others. They provide some context about the problem and ask for someone to help them get started or point them in the right direction. They also mention that the problem is from a specific book and apologize for posting in the wrong place. The response suggests writing both sides of the theorem as integrals and looking for cancellations.

I'm really struggling on even getting started on this problem. I have read the chapter several times now and I have tried to understand the explanations in the chapter. But I can't even get this problem started. All I ask is if anyone knows how to do this, can you just get me started or point me in the right direction so I can then take it from there?

Thanks for any help.

Prove the theorem <K|H|L> = (N!)1/2 <KHP|H|L>

where |KHP> is the Hartree product corresponding to the determinant |K>, i.e.

|K> = |Xm(X1)Xn(X2)...>

and

|KHP> = Xm(X1)Xn(X2)...

Prove this theorem

This problem is from "Modern Quantum Chemistry" by Szabo & Ostlund for anyone who is wondering.

I think I posted this question in the wrong part of these forums. I'm sorry about this.

Well, start by writing both sides out as integrals, which can be separated into sums of single-particle wave function-integrals, and see what cancels out.
