So i have
Sℕ = P(ℕ)
1. I need 3 elements of Sℕ that are finite sets. My idea:
Sℕ = {x | x < 4)
does that work?
2. I need to write down an element of Sℕ that is an infinite set.
Well, ℕ itself is already infinite ℕ=(1, 2,3,4,5......n)
So my answer would be:
Sℕ = {x | x € ℕ}
Correct? If not, would you like to correct me?
Thanks in advance!
