∻Solution by Steps∻ ‖ step 1 ⋮ To find the equivalent expression for $a^{-1}$, we refer to the rules of exponents. ‖ ‖ step 2 ⋮ According to the rules of exponents, $a^{-1}$ is equivalent to $\frac{1}{a}$. ‖ ‖ step 3 ⋮ This is confirmed by the asksia-ll calculation list, which states that the answer to $a^{-1}$ is $1/a$. ‖ ***C*** ∻Key Concept∻ ⚹Negative Exponent Rule⚹ ∻Explanation∻ ⚹The negative exponent rule states that $a^{-n} = \frac{1}{a^n}$, where $n$ is a positive integer. In this case, $a^{-1} = \frac{1}{a}$.⚹◊What is the correct equivalent expression for $a^{-1}$?⍭ Generate me a similar question◊
