Answer 2

(A')' = A

For any non-empty set A, (A')' = A.

Given:

A non-empty set A

To find:

(A')'

Step-by-step explanation:

Let x ∈ A

Then x ∉ A'

Then x ∈ (A')'

We have: x ∈ A ⇒ x ∈ (A')'

∴ A ⊆ (A')' ... ... (1)

Also, let y ∈ (A')'

Then y ∉ A'

Then y ∈ A

We have: y ∈ (A')' ⇒ y ∈ A

∴ (A')' ⊆ A ... ... (2)

From (1) and (2), we can conclude

(A')' = A
