Answer:
169
Explanation:
To apply the Laws of Exponents and write an equivalent expression for (-9-4)², we need to simplify the expression step by step.
First, let's simplify the expression (-9-4)²:
(-9-4)² = (-13)²
Next, we apply the exponent rule for a negative base. According to the rule, when a negative number is raised to an even exponent, the result is positive. So, we have:
(-13)² = 13²
Now, we can simplify 13² using the exponent rule for multiplication:
13² = 13 * 13 = 169
Therefore, the equivalent expression for (-9-4)² is 169.
