U = (6,-4,2)
V = (2,0,-6)
W = (-8,-4,-2)
(V+V) - W
((6,-4,2)+(2,0,-6) - W
(8, -4, -4) - (-8, -4, -2)
(40, -20,-20) + 9 (8,4,2)
(48, -16, -18)

5[6,-4,2) +(2,0,-6)]-(-8,-4,-2)
5[(6+2),(-4+0) ,(2-6)]-(-8-4,-2)
5(8,-4,-4)-(-8,-4,-2)
(40,-20,-20)-(-8,-4,-2)
[40-(-8)],[-20-(-4)],[-20-(-2)]
[40+8] , [-20+4],[-20+2]
(48,-16,-18)
5[(6+2),(-4+0) ,(2-6)]-(-8-4,-2)
5(8,-4,-4)-(-8,-4,-2)
(40,-20,-20)-(-8,-4,-2)
[40-(-8)],[-20-(-4)],[-20-(-2)]
[40+8] , [-20+4],[-20+2]
(48,-16,-18)
obrigado
