Algebra, VIII, p. 350, § 17. Reduced Norms and Traces

We have Nrd $_{E/K}(u) = 0$ if the element $u$ of E is not invertible (VIII, p. 340, Proposition 3).

Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
