i know that inrder to prove that one group of vectors are a part of another
i need to stack them up
and see that the "part of" vectors lines go to 0.
what is the general way of solving the second part of this question:

i know that in order to prove that one group of vectors are a part of another
i need to stack them up
i did row reduction and i dont know how to extract a vector for the group

this came from this question part 2

in the U group i have equations with "k"
i dont know what vectors to take?
