Math Problem Statement

Довести тотожність (A

Довести тотожність (A \cap \overline{B} \cup B = \overline{A} \cup B)

Solution

It seems you've uploaded an image with set theory and logic problems related to Venn diagrams. You specifically mentioned the task of proving the identity involving sets, starting with "A". I can see the following expression in the image:

ABB=ABA \cap \overline{B} \cup B = \overline{A} \cup B

This looks like a set theory identity that needs to be proven. Let's break it down:

Identity:

ABB=ABA \cap \overline{B} \cup B = \overline{A} \cup B

Proof:

  1. Left-hand side (LHS): [ A \cap
