Logic

I need help with these advanced excercises in logic. They're really hard, and my teacher said they should take at least a month.
Here's just one, if you can show me how I'm sure I'll be able to get the rest of them. There's apparently rules and stuff. I know V means or. ^ means and. ect+

1. Pv(Q^R)
2. S=>~R
3.~S=>S.'.X=>P
