Diketahui matriks k = [ 2 -1 ] dan L = [ 2 3 ] [ 3 4 ]

Pertanyaan:

Diketahui matriks k = [ 2 -1 ] dan L = [ 2 3 ]

[ 3 4 ] [ -1 2]
maka nilai k2 + L adalah…

Untuk mencari nilai K 2 + L cap K squared plus cap L K 2 + L , kita perlu mengkuadratkan matriks K cap K K (menghitung K × K cap K cross cap K K × K ) terlebih dahulu, lalu menjumlahkan hasilnya dengan matriks L cap L L , sehingga K 2 + L = [ 2 -1 3 4 ] [ 2 -1 3 4 ] + [ 2 3 -1 2 ] = [ 1 -6 18 13 ] + [ 2 3 -1 2 ] = [ 3 -3 17 15 ] cap K squared plus cap L equals the 2 by 2 matrix; Row 1: 2, negative 1; Row 2: 3, 4 end-matrix; the 2 by 2 matrix; Row 1: 2, negative 1; Row 2: 3, 4 end-matrix; plus the 2 by 2 matrix; Row 1: 2, 3; Row 2: negative 1, 2 end-matrix; equals the 2 by 2 matrix; Row 1: 1, negative 6; Row 2: 18, 13 end-matrix; plus the 2 by 2 matrix; Row 1: 2, 3; Row 2: negative 1, 2 end-matrix; equals the 2 by 2 matrix; Row 1: 3, negative 3; Row 2: 17, 15 end-matrix; K 2 + L = 2 − 1 3 4 2 − 1 3 4 + 2 3 − 1 2 = 1 − 6 1 8 1 3 + 2 3 − 1 2 = 3 − 3 1 7 1 5 .
