Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Radical Expressions
Radical expressions involve roots, such as square roots or cube roots. In this case, we are dealing with fifth roots, denoted as ⁵√. Understanding how to manipulate these expressions is crucial, as it allows us to simplify and combine them effectively, especially when they share the same index.

Radical Expressions with Fractions
Properties of Exponents
The properties of exponents are fundamental rules that govern how to handle expressions involving powers. For instance, when multiplying like bases, you add the exponents. This concept is essential for simplifying the product of radical expressions, as it allows us to express the radicals in terms of exponents, making calculations more straightforward.

Combining Radicals
Combining radicals involves using the properties of radicals to simplify expressions. When multiplying radicals with the same index, you can multiply the radicands (the numbers or expressions inside the radical) together. This principle is key to solving the given problem, as it enables the simplification of the product of the two fifth roots into a single radical expression.
