Final answer:
The 2-norm of a vector is computed using the Euclidean norm formula, which requires the square root of the sum of the squares of its components. However, the specifics of vectors C and D's components are unclear, making it difficult to provide an exact answer.
Step-by-step explanation:
The 2-norm of a vector, also known as the Euclidean norm, is a measure of its length in Euclidean space and is calculated by taking the square root of the sum of the squares of its components. To find the 2-norm for vectors C and D, we will apply the following formula:
||V||2 = √(v1² + v2² + v3²)
However, based on the information provided, there seems to be some missing or unclear elements, such as the exact components of vectors C and D. To proceed accurately, we would need the specific vector components for each.
