SOLVED: Discrete mathematics-Determine whether each of these arguments is valid. If anargument is correct, what rule of inference is being used? If it isnot, what logical error occurs?a) If n is a real number such that n > 1, then n2 > 1.Suppose that n2 > 1. Then n > 1.b) If n is a real number with n > 3, then n2 > 9. Supposethat n2 ≤ 9. Then n ≤ 3.c) If n is a real number with n > 2, then n2 > 4. Supposethat n ≤ 2. Then n2 ≤ 4.
