Question

Dados os vetores u = (1,3,2) e v = (2,1,4), o seu produto escalar é

Answer 1

$Ol\acute{a}~~\mathbb{MAGALI} \\ \\ \vec{u}.\vec{v}=(1,3,2).(2,1,4) \\ \\ \vec{u}.\vec{v}=1.2+3.1+2.4 \\ \\ \vec{u}.\vec{v}=\underbrace{2+3+8}_{13} \\ \\\boxed{ \boxed{\vec{u}.\vec{v}=13}}~---\ \textgreater \ produto~escalar \\ \\ \mathbb{vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Espero~ter~~ ajudado!!$
