Mohon bantuanya suhu ^^

|u| = √[6²+(-3)²+3²] = √54 = 3√6
|v| = √[(-2)²+(-4)²+2²] = √24 = 2√6
2|u| + |v| = 2 x 3√6 + 2√6 = 8√6 (D)

Mapel : Matematika
Kelas : X SMA
Bab : Vektor

Pembahasan :
2|u| + |v|
= 2(√[6² + (-3)² + 3²]) + (√[(-2)² + (-4)² + 2²])
= 2√54 + √24
= 2√9.6 + √6.4
= 6√6 + 2√6
= 8√6

Opsi D.
