1. The problem statement, all variables and given/known data
[(p>r) ^ (q>r)] > (p ^ q) > r 2. Relevant equations anything but a truth table! laws such as (p>q)= ~(p^~q) or (p>q)=(~q>~p) might help

See how far you get using the relevant equations you showed. Other relevant equations that will come in handy are DeMorgan's Laws, ~(p ^ q) <==> ~p V ~q, and ~(p V q) <==> ~p ^ ~q.
