Which of the following is a perfect square between 1 and 100?

Explanation:
A perfect square is a number that can be written as the product of an integer with itself. For numbers between 1 and 100, the perfect squares are 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100. Among the given numbers, 64 is a perfect square because it equals 8 × 8, so its square root is the integer 8. The other numbers aren’t squares since their square roots aren’t integers (approximately 4.24 for 18, 4.69 for 22, and 7.07 for 50). Therefore, 64 is the only perfect square in the set.
