Introduction

In mathematics, the cube root of a number is a value that, when multiplied by itself twice, gives the original number. In this article, we will explore the concept of cube roots and calculate the cube root of 2163\sqrt[3]{216}. We will delve into the world of mathematics, exploring the properties and applications of cube roots.

What is a Cube Root?

A cube root is a mathematical operation that finds the value that, when multiplied by itself twice, gives the original number. In other words, it is the inverse operation of cubing a number. For example, the cube root of 27 is 3, because 3 multiplied by itself twice gives 27 (3 × 3 × 3 = 27).

Properties of Cube Roots

Cube roots have several properties that make them useful in mathematics. Some of these properties include:

  • Existence: Every positive number has a cube root.
  • Uniqueness: Every positive number has a unique cube root.
  • Order: The cube root of a number is always positive.
  • Multiplication: The cube root of a product is the product of the cube roots.

Calculating the Cube Root of 2163\sqrt[3]{216}

To calculate the cube root of 2163\sqrt[3]{216}, we can use the following steps:

  1. Find the prime factorization of 216: The prime factorization of 216 is 2^3 × 3^3.
  2. Use the prime factorization to find the cube root: Since the prime factorization of 216 is 2^3 × 3^3, we can take the cube root of each factor separately. The cube root of 2^3 is 2, and the cube root of 3^3 is 3.
  3. Multiply the cube roots: The cube root of 216 is the product of the cube roots of each factor, which is 2 × 3 = 6.

Conclusion

In conclusion, the cube root of 2163\sqrt[3]{216} is 6. We used the properties of cube roots and the prime factorization of 216 to calculate the cube root. This example illustrates the importance of understanding the properties and applications of cube roots in mathematics.
