Introduction

In mathematics, finding a rational product involves multiplying two numbers to get a result that is a rational number. Rational numbers are numbers that can be expressed as the ratio of two integers, i.e., in the form of a/b, where a and b are integers and b is not equal to zero. In this problem, Reese needs to find a number that can be multiplied by $\sqrt[3]{12}$ to result in a rational product. This means that the product of the two numbers should be a rational number.

Understanding Cube Roots

A cube root of a number is a value that, when multiplied by itself three times, gives the original number. For example, the cube root of 27 is 3, because 3 × 3 × 3 = 27. In this problem, we are dealing with the cube root of 12, which is $\sqrt[3]{12}$ .

Properties of Cube Roots

Cube roots have some interesting properties that can help us find a rational product. One of the properties is that the cube root of a product is equal to the product of the cube roots. This means that $\sqrt[3]{ab} = \sqrt[3]{a} \times \sqrt[3]{b}$ .
