Question

Show that the product ABOUT of any two idealA and B of a ring R is an ideal of R

Answer 1

Step-by-step explanation:

An ideal I of R is said to be irreducible if it cannot be written as an intersection of two ideals of R which are strictly larger than I. Prove that if p is a prime ideal of the commutative ring R, then p is […] and its ideal P=(2,√10)={a+b√10∣a,b∈Z,2|a}.
