<p>We have learned the definition of the<a>cube</a>root. Now, let’s learn how it is represented using a<a>symbol</a>and<a>exponent</a>. The symbol we use to express the cube root is the radical sign (∛), and the exponent we use is ⅓. In<a>exponential form</a>, ∛-216 is written as (-216)^(1/3). The cube root is just the opposite operation of finding the cube of a<a>number</a>. For example: Assume ‘y’ as the cube root of -216, then y^3 can be -216. The cube root of -216 is -6, because (-6) × (-6) × (-6) = -216.</p>

<p>Let's find the cube root of -216 using the prime factorization method. The prime factorization of 216 is: 216 = 2 × 2 × 2 × 3 × 3 × 3 Therefore, -216 = -1 × 2 × 2 × 2 × 3 × 3 × 3 Grouping the<a>factors</a>in triples gives us: (-1 × 2 × 3) × (2 × 3) × (2 × 3) Thus, the cube root of -216 is -6.</p>

<p>Cube root: The number that is multiplied three times by itself to get the given number is the cube root of that number. Perfect cube: A number is a perfect cube when it is the product of multiplying a number three times by itself. A perfect cube always results in a whole number. For example, (-6) × (-6) × (-6) = -216, therefore, -216 is a perfect cube. Exponent: The exponent form of the number denotes the number of times a number can be multiplied by itself. In a^(1/3), ⅓ is the exponent which denotes the cube root of a. Radical sign: The symbol that is used to represent a root, expressed as (∛). Rational number: A number that can be expressed as a fraction or ratio, where both the numerator and the denominator are integers. The cube root of -216 is rational because it is -6.</p>
