Show, that if f n → f and f n → g is μ-convergent, then...
Show, that if and is -convergent, then almost everywhere on
Use the fact, that:
So, I don't know how to use that hint. μ convergent means (correct me if I'm wrong), that
So I don't see it how the hint should be used.
It is not written what kind of measure our is though, usually when there's nothing written we assume it's a Lebesgue measure, but I don't know if that has to be the case here
