Loi used these steps to simplify the expression (StartFraction (x cubed) (y Superscript negative 12 Baseline) Over 2 (x Superscript negative 3 Baseline) (y Superscript negative 3 Baseline) EndFraction) Superscript negative 2. Step 1: Subtract the exponents of powers with like bases. (StartFraction x Superscript 6 baseline y Over 2 EndFraction) Superscript negative 2 Step 2: Apply the power of a product rule. StartFraction x Superscript negative 12 Baseline y Superscript negative 2 Baseline Over 2 Superscript negative 2 Baseline EndFraction Step 3: Write negative exponents as reciprocals using positive exponents. StartFraction 1 Over 2 squared x Superscript 12 Baseline y squared EndFraction Step 4: Evaluate the power with the integer base. StartFraction 1 Over 4 x Superscript 12 Baseline y squared EndFraction In which step did Loi make the first error? Step 1 Step 2 Step 3 Step 4
