Which expression is equivalent to \( \frac{2^{-3}}{2^{-5}} \) ? (A) \( 2^{2} \) (B) \( \frac{1}{2^{2}} \) (C) \( 2^{8} \) (D) \( \frac{1}{2^{8}} \)

Calculate or simplify the expression \( \frac{2^{-3}}{2^{-5}} \). Calculate the value by following steps: - step0: Calculate: \(\frac{2^{-3}}{2^{-5}}\) - step1: Multiply by \(a^{-n}:\) \(2^{-3}\times 2^{5}\) - step2: Multiply: \(2^{-3+5}\) - step3: Add the numbers: \(2^{2}\) - step4: Evaluate the power: \(4\) The expression \( \frac{2^{-3}}{2^{-5}} \) is equivalent to \( 4 \). Therefore, the correct answer is (A) \( 2^{2} \).
