Question Analysis
This problem assesses the ability to simplify a radical expression by factoring the radicand and applying the properties of radicals.

Key Concept Explanation
To simplify a radical expression, we factor the radicand into a product of a perfect power and another factor. For square roots, we look for perfect squares.

Step-by-step Solution
1. Factor the radicand: , where
2. Separate the perfect square from the remaining factor:
3. Apply the property of radicals:
