Subject: Need help w/ problem

Hi all, back at math after a couple years break (even though I dont think the math I took would help with this). Anyway I'm just starting out with propositional equivalences and i needed help with this more intermediate problem. Any help would be greatly appreciated :) 
Show that the compound propositions
¬p V ¬q V ¬r and ¬p V (r -> ¬q)
are equivalent.
