The GCF is: 1
4piR2 = 4pi*16 = 2001
2003 The first digit cannot be zero because then the number would be less than 1459. Similarly the first digit cannot be greater than 2 because then the number would be more than 2569. Therefore, the first digit must be 2. Then, so far, we have 20__. We see now that any number in this range is greater than 1459 and less than 2569. So a complete answer would be 2000, 2001, 2002, ..., 2099.
"The present list of 19 rules of inference constitutes a COMPLETE system of truth-functional logic, in the sense that it permits the construction of a formal proof of validity for ANY valid truth-functional argument." (FN1)The first nine rules of the list are rules of inference that "correspond to elementary argument forms whose validity is easily established by truth tables." (Id, page 351). The remaining ten rules are the Rules of Replacement, "which permits us to infer from any statement the result of replacing any component of that statement by any other statement logically equivalent to the component replaced." (Id, page 359).Here are the 19 Rules of Inference:1. Modus Ponens (M.P.)p qpq 2.Modus Tollens (M.T.)p q~q~p 3.Hypothetical Syllogism (H.S.)p qq rp r 4.Disjunctive Syllogism (D.S.)p v q~ pq 5.
