Ermine whether a is diagonalizable. a = 4 0 4 0 4 4 4 4 0 yes no correct: your answer is correct. find an invertible matrix p and a diagonal matrix d such that p−1ap = d. (enter each matrix in the form [[row 1], [row 2], , where each row is a comma-separated list. if a is not diagonalizable, enter no solution.)
