Concept:

We are given a Boolean function in the nested form: . To simplify this, we need to understand how the function behaves and use Boolean algebra rules.

Step 1: Assume definition of function

Let us assume , a common definition used in Boolean simplification unless otherwise specified.

So,

Using the identity: (Since )

Step 2: Substitute into outer function

Now substitute into the outer function:

Hence, the simplified expression is:
