## Let I be an unmixed radical ideal of R. then (I:x) is unmixed November 28 1

Let $R$ be commutative ring with $1$. One says that an ideal $I$ is unmixed if $I$ has no embedded prime divisors (in other words, if the associated prime ideals of $R/I$ are the minimal prime ideals of $I$). Let $I$ be an unmixed radical ideal of $R
