2 votes 2 votes If x1, x2, x3,.....xn be the eigen values of a matrix A. Then the eigen values of An are x1n, x2n , x3n .....xnn So here the eigen values of A are 2 and -3. So eigen values of A2 will be (2)2 = 4 and (-3)2 = 9 . Jithin Jayan answered Nov 11, 2016 Jithin Jayan comment Share Follow See all 0 reply Please log in or register to add a comment.
