Between which two integers is √14 located?

Answer and explanation

Correct answer: 3 and 4

The governing idea is comparison with consecutive perfect squares. We know that 3² = 9 and 4² = 16. Since 9 < 14 < 16, taking principal square roots preserves the order and gives 3 < √14 < 4. Hence √14 is located between the integers 3 and 4, so option C is correct. It cannot be between 2 and 3 because every number strictly between 2 and 3 has a square between 4 and 9, whereas 14 is larger than 9. It cannot be between 4 and 5 because 4² is already 16, which is greater than 14. Numerically, √14 is approximately 3.74, confirming the interval.
