Diketahui vektor u = [1,-3,-2], v = [1,1,0], dan w = [2,2,-4].hitunglah

Jawaban Terkonfirmasi

A) u + u = (1, -3, -2) + (1, -3, -2) = (2, -6, -4)
|u + u| = √(2^2 + (-6)^2 + (-4)^2) = √(4 + 36 + 16) = √56 = 2√14

b) u + v + w = (1, -3, -2) + (1, 1, 0) + (2, 2, -4) = (4, 0, -6)
|u + v + w| = √(4^2 + 0^2 + (-6)^2) = √(16 + 0 + 36) = √52 = 2√13
