Commutative Algebra, chapter VI, § 8. Extensions of a valuation to an algebraic extension

If v is discrete, ε(vi′/v)=ε(vi′/v)\varepsilon(v'_i/v) = \varepsilon(v'_i/v) (no. 4) and condition (d) reduces to ∑i=1sε(vi′/v)f(vi′/v)=n.\sum_{i=1}^s \varepsilon(v'_i/v) f(v'_i/v) = n.

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
