Here are the essential concepts you must grasp in order to answer the question correctly.
Negative Exponents
Negative exponents indicate the reciprocal of the base raised to the absolute value of the exponent. For example, a^-n = 1/a^n. This concept is crucial for rewriting expressions without negative exponents, as it allows us to transform them into a more standard form that is easier to evaluate.

Reciprocal
The reciprocal of a number is defined as 1 divided by that number. In the context of exponents, when dealing with negative exponents, we take the reciprocal of the base raised to the positive exponent. For instance, (1/3)^-2 becomes 3^2, which simplifies the expression for evaluation.

Evaluating Expressions
Evaluating an expression involves calculating its value based on the given numbers and operations. In this case, after rewriting the expression without negative exponents, we can substitute the values and perform the necessary arithmetic operations to find the final result, ensuring clarity and accuracy in the solution.
