Question Analysis
This problem assesses the ability to simplify radical expressions by dividing the radicands and simplifying the result.

Key Concept Explanation
When dividing two radicals with the same index, the quotient of the radicands becomes the new radicand. The simplified form should be a whole number if possible.

Step-by-step Solution
1. Confirm conditions: Index = 2 (even); radicands 128 ≥ 0, 8 > 0; same index.
2. Apply division property:
