Jawab:
vektor
operasi
[tex]\sf \vec{a}= ~\dbinom{-4}{-2}~~dan~~ \vec{b}= ~\dbinom{1}{4}[/tex]
hasi dari
[tex]\sf = 3\vec{b} -\dfrac{1}{2}\vec{a}[/tex]
[tex]\sf = 3 ~\dbinom{1}{4} - \frac{1}{2}~\dbinom{-4}{-2}~[/tex]
[tex]\sf = ~\dbinom{3}{12} +~\dbinom{2}{1}~[/tex]
[tex]\sf = ~\dbinom{3+2}{12+1} = \dbinom{5}{13}[/tex]
