Math Problem Statement

Solution

To solve the problem, we need to determine the approximate value of 14\sqrt{14} and then find the correct interval from the given options.

Step 1: Estimate 14\sqrt{14}

The square root of 14 is a number between the square roots of 9 and 16 because: 9=3and16=4\sqrt{9} = 3 \quad \text{and} \quad \sqrt{16} = 4 So, 14\sqrt{14} is between 3 and 4.

Step 2: Refine the Estimate

To get a better estimate, you can calculate or remember that: 143.74\sqrt{14} \approx 3.74

Step 3: Choose the Correct Interval

Given the options:

  1. Between 4-4 and 5-5
  2. Between 2-2 and 3-3
  3. Between 3-3 and 4-4
  4. Between 1-1 and 2-2

Since we need the value of 14-\sqrt{14}, we negate the positive value: 143.74-\sqrt{14} \approx -3.74 This value falls between 4-4 and 3-3.

Conclusion

The correct answer is the third option: Between 3-3 and 4-4.
