I don't quite understand bases in this question, since we expect column space to have 1 dimension and if it has 2 dimension, then there wouldnt be any N(A). Looking at explanation, I don't understand why dimensions should add up to 4? n=m=2 and we expect it to add up to 2. Would anyone please explain what's going on in this question?

The attachment is very difficult to read.

Is the problem the same as problem 33 in this document?
