Question

(A intersection B) subset A​

Answer 1

Step-by-step explanation:

Suppose AA and BB are sets. Prove that A⊆BA⊆B if and only if A∩B=AA∩B=A.

Here's how I see it being proved.

If AA and BB are sets,and the intersection of AA and BB is equal to AA, then the elements in AA are in both the set AA and BB. Therefore, the set of AA is a subset of BB since all the elements are contained in the interesection of sets AA and BB are equal to AA.

Can I prove it that way?
