Hello there,
I have troubles with finding equivalence classes for my homework.
Question goes like this:
Let A={1,2,3,4} and B = {2,4}. P(A) is power set. Relation R defined on P(A) by
X R Y, X, Y elements of P(A) if X ∩ B = Y ∩ B. Now, i have to show that R is equivalence relation on P(A), which i did. and i have to find equivalence classes for R.
Now, im stuck here.. im not too sure how start it. I was wondering if you could guide me please.
Thank you in advance.
