Question Analysis
This problem evaluates the student's ability to multiply radical expressions with coefficients and simplify the result.

Key Concept Explanation
When multiplying two radical expressions with the same index, the product of the radicands serves as the new radicand, and the product of the coefficients outside the radicals becomes the new coefficient. The formula is: .

Step-by-step Solution
1. Separate coefficients and radicals:
2. Multiply the coefficients:
