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.

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
