Question
**Evaluate the Factorial Expression**

Consider the expression \((7 - 4)!\).

To solve this, we first simplify the expression in the parentheses:

\[7 - 4 = 3\]

Now, we need to evaluate the factorial of 3, denoted as \(3!\). 

The factorial function is the product of all positive integers up to a given number \(n\). Thus, for \(3!\):

\[3! = 3 \times 2 \times 1 = 6\]

In the image, it appears there is an error in the evaluation step where \( (7-4)! \) is erroneously calculated as 5,016. The correct calculation is:

\[ (7-4)! = 3! = 6 \]

No graphs or diagrams are present in the image.
