# Math Help - Perform operations on vectors

1. ## Perform operations on vectors

perform the indicated operations, where u=<-2,4> and v=<-3,-2>
[[v+2u]]
(the brackets[] are supposed to be straight lines indicating magnitude)

$|<-2,4>+2<-3,-2>|=|<-2,4>+<-6,-4>|=$
$|<-8,0>|=\sqrt{(-8)^2+(0)^2}=\sqrt{64}=8$
