Considering p, r and q are statements, use logic laws to indicate: (pvq) →r ≡ (p→r) ᴧ (q→r) By using logic laws, determine if the statement below is a contradiction, tautology or neither. [p→(q→p)] ↔ (pᴧ¬p) By using logic laws, test if the argument below is valid: Either I exercise regularly, or I eat healthy. If I exercise regularly then I will not get fat. I got fat. Therefore, I am healthy.
