Math Problem Statement

Complete the following statement. Use the integers that are closest to the number in the middle: __ < ∛14 < __

Solution

To complete this problem, we need to evaluate the cube root of 14, 143\sqrt[3]{14}, and determine the closest integers on either side of this value.

  1. First, calculate 143\sqrt[3]{14}: 1432.41\sqrt[3]{14} \approx 2.41

  2. Identify the integers closest to 2.41:

    • The integer immediately less than 2.41 is 2.
    • The integer immediately greater than 2.41 is 3.

Thus, the completed statement is: 2<143<32 < \sqrt[3]{14} < 3

Would you like a more detailed breakdown or further explanation? Here are some follow-up questions for practice:

  1. What is the cube root of 27, and what integers would surround it?
  2. How would you solve for the cube root of a non-perfect cube, like 20?
  3. How does a cube root differ from a square root in terms of calculation and interpretation?
  4. What is the general formula for finding the nn-th root of a number?
  5. Why is 143\sqrt[3]{14} approximately 2.41, and how can we find a more precise value?

Tip: To approximate cube roots of non-perfect cubes, try estimating between known perfect cubes (like 83=2\sqrt[3]{8} = 2 and 273=3\sqrt[3]{27} = 3).
