Explicación paso a paso:
Datos:
u = (2 ,-3)
v = (0 ,4)
w = (-1 ,3)
a) u +v +w
(2 ,-3) + (0 ,4) + (-1 ,3)
( 2 + 0 -1 , -3 + 4 +3)
( 1 , 4)
b) 2u -3v + 4w
2(2 ,-3) -3(0 ,4) + 4(-1 ,3)
( 4 , -6) - ( 0 , 12) + (-4 , 12)
( 4 - 0 -4 , -6 -12 + 12)
(0 , -6)
c)2u
2(2 ,-3)
( 4 , -6)
d)2u * (-4w)
2(2, -3)* [-4(-1,3)]
2(2, -3)* [(4, -12)]
(4 , -6) * (4, -12)
(4*4 )+ (-6*-12)
16+ 72
88
e)v*3w
(0 ,4) * 3(-1 ,3)
(0 ,4) * (-3 ,9)
0*-4 + 4*9
0 + 36
36
