Answer 2

It seems like you're trying to perform an operation involving vectors, but the notation is a bit unclear. In vector notation, you typically have components separated by commas or within angle brackets. However, the notation you've provided doesn't seem to follow the usual vector addition format.

Could you please clarify the notation you're using? Specifically, how are the vectors represented and what operation are you trying to perform? This will help me provide you with the correct answer.
