Chapter 10: Commutative Algebra > Section 10.150: Henselization and strict henselization

**Henselization is compatible with quotients.**

Lemma 10.150.10. Let $R$ be a local ring with henselization $R^h$. Let $I \subset \mathfrak m_R$. Then $R^h/IR^h$ is the henselization of $R/I$.

Proof.This is a special case of Lemma 10.150.9. $\square$
