The text extraction did not yield a proper result, but from visually analyzing the image, the mathematical expression seems to be:

$-4 \cdot (-2)^2 - 2^3$

Let's solve this step by step:

Step 1: Compute the powers

• $(-2)^2 = (-2) \times (-2) = 4$
• $2^3 = 2 \times 2 \times 2 = 8$

Step 2: Multiply the results

• $-4 \cdot 4 = -16$

Step 3: Final subtraction

Now subtract $8$ from $-16$: $-16 - 8 = -24$

Final Answer:

$-24$
