Answer: Yes
Step-by-step explanation: 9 is a perfect square. In other words, it's possible to find a whole number that can be multiplied by itself which gives us 9. In this case, the number would be 3 since 3 × 3 or 3² gives us a product of 9.
3 is a natural number and all natural numbers are contained within the set of rational numbers. Therefore, the square root of 9 is rational.
