Question

Analyze the following argument

If n is a real number such that n>2 , then n^2 >4 . Suppose that n less than or equal to 2, then n^2 is less than or equal to 4.

a) it is valid
b) It is not valid because it begs the question
c) It is not valid because it denies the hypothesis
d) It is not valid because it affirms the conclusion

Answer 1

c) it is invalid because it denies the hypothesis. Additionally, the conclusion of the statement turns out to be false: -3≤2, but (-3)²=9>4.
