Answer 1

☺ Eigenvalues of 003] =A(say) s lAnd I)=0 23 land a lso o ud2420 3 d = 12 So, spectral = Eigenvalues radius = max{1+21, 1-21} = 2 of 1027 = B(say). - - s B-dat-o u i-d a lo e-A (4-d) -0 =0 ० ५- Y ५ -1) 50. edzo, d=4 & max (10), 141} -- - a spectral radius 6 w So z 4=2 & d = 4 ya [value] x2 Y [value J ...2 Rodeo
