Diketahui vektor p = 3i + 2j + ak, q = i + bj – 3k, dan r = i + (a – 2)j + 2k. Jika p + q = 4r,
Diketahui vektor p = 3i + 2j + ak, q = i + bj – 3k, dan r = i + (a – 2)j + 2k. Jika p + q = 4r, tentukan nilai a dan b!
Jawab:
p = 3i + 2j + ak,
q = i + bj – 3k, dan
r = i + (a – 2)j + 2k
p + q = 4r,
a = .... ?
b = .... ?
Jawab:
p = 3i + 2j + ak,
q = i + bj – 3k, dan
r = i + (a – 2)j + 2k
p + q = 4r,
a = .... ?
b = .... ?
Jadi nilai a = 11 dan nilai b = 34
