OP warned about not having an attempt at a solution

## Homework Statement

δ(z*-z0*)δ(z+z0)=?

δ(z*+z0*)δ(z-z0)=?

where 'z' is a complex variable 'z0' is a complex number

Formula is just enough, derivation is not needed.

The product of distributions is not in general well defined, see here. You can multiply a distribution by a smooth function, but not in general by another distribution.

So the expressions above do not have a clear meaning. They are not well-defined.
