To put it another way, you know that there has to be one, since (because is transitive), so we can call it , and it’s uniquely defined (-a.e.). But the product satisfies the same condition as : you can get the -measure of any set by integrating either or with respect to over . So they’re equal -a.e. and must be integrable, and so it’s as good a representative for the Radon-Nikodym derivative as any.
