hey guys, i need help coding B) and C) and easy code using python please l.

Nilpotent Matrices 1. A matrix MMnn is called nilpotent if there is a positive integer n such that Mn=0, where 0 is the zero matrix. a) Let BMnn be a nilpotent matrix, such that Bn=0. Calculate (InB)(In+B+B2+Bn1) (no Python required). b) Show that the following matrices are nilpotent by finding the value of n such that Mn=0. Use Python to find the powers of the matrices. A=251215233B=2611216121163444C=2711121711211712111745555 c) Use (a) to calculate the inverse of the matrices i) I3A, ii) I4B iii) I5C, where A,B and C are the matrices from (b)
