thank you very much for explaining it to me. i understand why it's a true claim and your elaborate answer helped a lot to know how to approach such questions

How do i know if this claim is ture? #{v_1,...,v_n}# base of # V# and #T:Vâ†’V# follows:#T_{v_1}=0#, #T_{v_i}=v_(iâˆ’1)# #(2â‰¤iâ‰¤n)#, so there exists #T^k=0# in #1â‰¤k<n#?(quite urgent)

How do i know if this claim is correct: #A \in M_{nxn}^F# matrix that cannot be diagonalized. can there exist a polynom p(t)âˆˆF[t] of degree less than n so that #[p(A)]^2=0# when a)F=C or b) F = R?
