#-8vecu = <8, -32>#

Explanation:

We're given two vectors

#vecu = <-1,4>#

#vecv = <3,-2>#

and asked to find the value of #-8vecu#, so vector #vecv# I'm assuming is irrelevant..

Vector #vecu# multiplied by the scalar quantity #-8# is thus

#<-8(-1), -8(4)>#

#= color(blue)(ulbar(|stackrel(" ")(" "<8, -32>" ")|)#
