To simplify the expression \((A \land B) \lor (C \lor B) \lor (C \land B)\), we can apply logical identities.

  1. Recall that:
    • \(\land\) represents logical AND
    • \(\lor\) represents logical OR

Let's break it down step by step:

  1. Expand the expression:

    \((A \land B) \lor (C \lor B) \lor (C \land B)\)

  2. Using the distributive property, we recognize that \((C \lor B)\) can be simplified as follows:

    • \(C \lor B\) is already in its simplest form, so we can just include both terms.
  3. Rearranging the expression, we distribute \(B\) across \((C \land B)\):

    \((A \land B) \lor (C \lor B) \lor (C \land B)\) can be rearranged to:

    \[ = (A \land B) \lor ((C \land B) \lor C) \lor B \]

  4. Now using the Absorption Law, we can simplify it:

    • \(C \lor (C \land B) = C\) since \(C\) covers both cases.

This leads us to:

\[ = (A \land B) \lor C \lor B \]

  1. Finally, we can see if \(B\) can be absorbed:
    • The expression becomes \((A \land B) \lor C \lor B = (C \lor B)\) since \(B\) is common.

Thus, the entire expression can be simplified to:

\[ C \lor B \]

This means that the original expression simplifies down to:

\[ B \lor C \]

In summary, \[ (A \land B) \lor (C \lor B) \lor (C \land B) \equiv B \lor C \]
