1. The problem statement, all variables and given/known data If A is an nxn matrix such that A^3 = 0 (the zero matrix) then (I-A)^-1 = ...? A. not invertible B. I+A^2 C. I-A D. I+A E. I+A+A^2 2. Relevant equations 3. The attempt at a solution I just don't know how to work out what the inverse of (I-A) is if I know A^3... how is this even helpful?? It's a multichoice question and apparently the answer is 'E'
