Given A = `[(0, 4, 6),(3, 0, -1)]` and B = `[(0, 1),(-1, 2),(-5, -6)]`, find if possible BA
Given A = `[(0, 4, 6),(3, 0, -1)]` and B = `[(0, 1),(-1, 2),(-5, -6)]`, is the following possible BA
उत्तर
BA = `[(0, 1),(-1, 2),(-5, -6)][(0, 4, 6),(3, 0, -1)]`
= `[(0 + 3, 0 + 0, 0 - 1),(0 + 6, -4 + 0, -6 - 2),(0 - 18, -20 - 0, -30 + 6)]`
= `[(3, 0, -1),(6, -4, -8),(-18, -20, -24)]`
