Question

Sejam u = (5,-1,0,3,-3), v = (-1, -1,7,2,0) e w = (-4,2,-3, -5,2). Encontre os componentes de -2(3w+v) + (2u+w)

Answer 1

Resposta:

3w+v = (-12 , 6 , -9 , -15 , 6) + (-1, -1,7,2,0) =(-11 , 5 , -2, -13 , 6)

-2*(3w+v)= (22,-10, 4 ,26 ,-12)

(2u+w) =(10 , -2, 0 , 6, -6) + (-4,2,-3, -5,2) =(6 , 0 , -3 ,1 , -4)

-2(3w+v) + (2u+w) = (22,-10, 4 ,26 ,-12) + (6 , 0 , -3 ,1 , -4)

= ( 28 , -10 , 1, 27 , -16)
