Choose the correct statement about the set {n² : n ∈ N}.
Answer and explanation
Correct answer: It is infinite
For every natural number n, the set contains the square n². Its beginning is 1, 4, 9, 16, 25, and so on. As n can be chosen arbitrarily large, the squares continue without an ending largest element. Also, different natural numbers give different squares, so infinitely many distinct elements occur. Therefore the set is infinite.
