Question

Sendo A=(1 3 2-2), B=(0 -2 1 4) e C=(1 -2 3 4) Determine 2A-(B+C)

Answer 1

Resposta:

Temos A = (1, 3, 2, -2), B = (0, -2, 1, 4) e C = (1, -2, 3, 4)

2 x A = 2 x (1, 3, 2, -2) = (2, 6, 2, -4)

B + C = (0, -2, 1, 4) + (1, -2, 3, 4) = (0 + 1, -2 + (-2), 1 + 3, 4 + 4) = (1, -4, 4, 8). Assim,

2 x A + (B + C) = (2, 6, 2, -4) + (1, -4, 4, 8) = (2 + 1, 6 + (-4), 2 + 4, -4 + 8) = (3, 2, 6, 4)
