Question

7. Show that the following conditional statement is a tautology without using truth
tables.[p ∧ (p → q)] → q

Answer 1

Said in a very "basic" way

You are saying two things with the ^

1) p is there

AND (the ^)

2) if p is there, q is there

So finally we conclude that q must be there because we were told that if p was there q was there, and (because of the ^) we were also told that p was there
