Diketahui vektor a=3i+4j-6k dan vektor b= 2i+3j-2k

Jawaban:

a.vektor a=3i+4j-6k

vektor b=2i+3j-2k

*jwb: (3-2)i (4-3)j (-6-2)k

= i+i-8ky

b. 2vektor a-vektor b

*jwb:2(3i+4j-6k)-(2i+3j-2k)

=(6i+8j-12k)-(2i+3j-2k)

=4i+5j-10k

c.3a-2b

*jwb:3(3i+4j-6k)-2(2i+3j-2k)

=(9i+12j-18k)-(4i+6j-4k)

=5i+6j-14k
