1. **State the problem:** Simplify and evaluate the expression $$\left(-5 - 2(8 - 4 \times 3)\right)^2 \times 0$$. 2. **Apply order of operations (PEMDAS):** Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). 3. **Evaluate inside the parentheses:** Calculate the multiplication inside the parentheses first: $$8 - 4 \times 3 = 8 - 12 = -4$$ 4. **Substitute back:** $$-5 - 2(-4)$$ 5. **Multiply:** $$-5 - \cancel{2} \times \cancel{(-4)} = -5 + 8$$ 6. **Simplify:** $$-5 + 8 = 3$$ 7. **Square the result:** $$3^2 = 9$$ 8. **Multiply by 0:** $$9 \times 0 = 0$$ **Final answer:** $$0$$
