Question

Vec a =\ 1 ; 12} и b = {-2; n} &

Answer 1

It looks like you've provided two vectors, a and b, but there might be some formatting issues in your input. Vectors are typically represented as ordered lists of numbers enclosed in square brackets. Additionally, it seems there's an '&' symbol at the end of your input, which is not clear in the context of vectors.

If you meant to represent vectors a and b as follows:

Vector a: [1, 12] Vector b: [-2, n]

Then, these are two 2-dimensional vectors. Vector a has specific numerical values in its components, while vector b has a variable 'n' in its second component, which means the value of 'n' is not specified and can take any real number.

If you have any specific questions or operations you would like to perform with these vectors, please provide more details, and I'll be happy to assist you further.
