Diketahui bahwa vektor a= (-2/4) dan b= (-3/2) tentukan a-2b

a-2b
= (-2/4) - 2(-3/2)
= (-1/2) + 6/2
= 5/2

[tex]a = - \frac{2}{4} \\ b = - \frac{3}{2} \\ \\ \\ a - 2b = - \frac{2}{4} - 2( - \frac{3}{2} ) \\ = - \frac{2}{4} + \frac{6}{2} \\ = - \frac{2}{4} + 3 \\ = - \frac{2}{4} + \frac{12}{4} \\ = \frac{10}{4} \\ = \frac{5}{2} [/tex]
