Final answer:
To simplify the expression (-2)² - 24 ÷ (15-9), evaluate the exponents, simplify the subtraction, and then perform the division.
Step-by-step explanation:
To simplify the expression (-2)² - 24 ÷ (15-9), we begin by evaluating the exponents. (-2)² equals 4. So the expression becomes 4 - 24 ÷ (15-9). Next, we simplify the subtraction in the parentheses. 15-9 equals 6. The expression now becomes 4 - 24 ÷ 6. Finally, we divide 24 by 6 and subtract the result from 4. 24 ÷ 6 equals 4, so the expression simplifies to 4 - 4, which equals 0.
