Answer

Explanation:

Step1: Recall negative - exponent rule

The rule for a negative exponent is (a^{-n}=\frac{1}{a^{n}}), where (a\neq0) and (n) is a positive integer. Here (a = 2) and (n = 1). So (2^{-1}=\frac{1}{2^{1}})

Step2: Simplify the expression

Since (2^{1}=2), then (\frac{1}{2^{1}}=\frac{1}{2})

Answer:

(\frac{1}{2})
