The expression extracted from the image is:

$\frac{23 + 5}{18 - 4^2}$

Let's solve this step by step:

1. First, solve the numerator: $23 + 5 = 28$.
2. Next, solve the denominator: $4^2 = 16 \quad \text{so} \quad 18 - 16 = 2.$
3. Finally, divide the numerator by the denominator: $\frac{28}{2} = 14.$

The final result is $14$.
