The expression you provided seems to be describing a set-theoretic identity. Let's break it down:

1. \( I \setminus (A \setminus B) \): This represents the set difference between \( I \) and \( A \setminus B \), where \( A \setminus B \) refers to the elements in \( A \) but not in \( B \).

2. \( I \setminus A \cap B \): This expression represents the intersection of the complement of \( A \) (relative to \( I \)) and the set \( B \).

### To check if these two expressions are equal, let's analyze:

#### Left-hand side: \( I \setminus (A \setminus B) \)
- \( A \setminus B \): The set of elements in \( A \) but not in \( B \).
- \( I \setminus (A \setminus B) \): The set of elements in \( I \) that are not in \( A \setminus B \). In other words, it's the complement of \( A \setminus B \) with respect to \( I \).

#### Right-hand side: \( I \setminus A \cap B \)
- \( I \setminus A \cap B \): The set of elements in \( I \) that are not in both \( A \) and \( B \) at the same time.

### Equality check:
1. The left-hand side, \( I \setminus (A \setminus B) \), simplifies to the elements in \( I \) that are either in \( B \) or not in \( A \).
2. The right-hand side, \( I \setminus A \cap B \), simplifies to the elements in \( I \) that are either not in \( A \), or not in \( B \), or both.

Thus, **both sides are equivalent**, meaning:
\[
I \setminus (A \setminus B) = I \setminus A \cap B
\]

This is a valid set-theoretic identity.
