3.2 #24
When a vector [V] is in the span of Ker(A), it means that the linear transformation of [V]([A])=the zero vector.
So... The vector that makes the vector A zero is in the span of Ker(A)
3.2 #28
Use theorem 3.2.4.
But first determine whether each column is linearly independent.
3.2 #45
Use summary 3.1.8 on Pg. 109
Note that ker(A)=zero vector, that means all columns in A are linearly independent.
3.3 #28
to form a basis of R4, the RREF of A must be I4.
