3. Let T be a linear transformation of R" to R" given by T(v) = Av for some n x n matrix A.
a)
Prove ker T C kerT² C kerT³ C …..
Note: ker T" = nullspace of A"
b) If kerT = ker T2, show that in general we must have ker T" = ker Tn+l for all n> 1.
c) Use this result ( i.e., ( b) ) to show that there is no 3 × 3 matrix X such that
