G. span{a₁, az, aș, a4} = R³
H. {a₁, az, as, a4} is a linearly independent set
b. If possible, write as as a linear combination of a₁ and a2; otherwise, enter DNE. Enter a1 for a₁, etc.
a3 = -4a1+a2
c. If possible, write a as a linear combination of a, a, and as; otherwise, enter DNE
a4 = 5a1+3a2+a3
d. The dimension of the column space of A is 2
