If A = `[(1, 2),(3, 4)]`, B = `[(6, 1), (1, 1)]` and C = `[(-2, -3),(0, 1)]`, find the following and state if they are equal CA + B
उत्तर
CA = `[(-2, -3),(0, 1)][(1, 2),(3, 4)]`
= `[(-2 - 9, -4 - 12),(0 + 3, 0 + 4)]`
= `[(-11, -16), (3, 4)]`
CA + B = `[(-11, -16),(3, 4)] + [(6, 1),(1, 1)]`
= `[(-5, -15),(4, 5)]`
