(adsbygoogle = window.adsbygoogle || []).push({}); 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'
