An ancient culture labeled certain numbers as square numbers. The numbers 1, 4, 9, 16, 25, and so on are square numbers. Is 72 a square number? Explain how you determined your answer.
No, because it falls between two square numbers, 8 squared and 9 squared, and there is no natural number between 8 and 9.
