Let v=[3,3,−4,−7]. Find a basis of the subspace of R4 consisting of all vectors perpendicular to v.

Let u = [1,0,2−4], V=[0,1,−9,−9], and let W the subspace of R4 spanned by {u,v}. Find a basis for W⊥.

Question:For a subset E of R and a number a ∈ R, let a+E = {a+e | e ∈ E}. Show that E is measurable if and only if a+E is measurable.My approach:==>Suppose E is L. measurable.Then a+E = a union... more
