Math Problem Statement
Solution
To solve the problem, we need to determine the approximate value of and then find the correct interval from the given options.
Step 1: Estimate
The square root of 14 is a number between the square roots of 9 and 16 because: So, is between 3 and 4.
Step 2: Refine the Estimate
To get a better estimate, you can calculate or remember that:
Step 3: Choose the Correct Interval
Given the options:
- Between and
- Between and
- Between and
- Between and
Since we need the value of , we negate the positive value: This value falls between and .
Conclusion
The correct answer is the third option: Between and .
