To solve this problem, we will follow the standard rule for evaluating expressions with negative exponents:
Now, let's proceed through each step:
Step 1: The expression within the parentheses is , which simplifies to or further reduced to . However, for the purpose of matching the choices given, we'll use the product form directly.
Step 2: Apply the negative exponent formula:
Step 3: The result of this step shows the reciprocal raised to the power of 2:
The solution to the problem is therefore represented as:
.
Upon reviewing the choices provided, this corresponds to choice 1.
