Question

A. If B is a basis for a subspace H, then each vector in H can be written in only one way as a linear combination of the vectors in B.
b. If B= {V1,..... Vp} is a basis fora subspace H of Rn, then the Correspondence X →[X]B makes H look and act the same as IRE.
c. The dimension of Nul As the number of variables in the equation Ax=0.
