I hope I'm not breaking any rules by posting this, but just came across a homework problem that I was unsure on.

What is the Cartesian product of A and the power set of B if A={1} and B={}?

I know that the Cartesian product of A x B under these cases is the empty set, but it's not the same thing.

So far I've tried looking at it a few different ways: {1} x {{}}= ? being one

Thank you
