Not simplifying negative exponents

✏️ 3 Solved PYQs

Question 1: Simplify (2³)² Step 1: Use the power rule for exponents Step 2: (2³)² = 2³×² = 2⁶ Step 3: Evaluate 2⁶ = 64 Answer: 64
Question 2: Simplify (3²)⁻¹ Step 1: Use the power rule for exponents Step 2: (3²)⁻¹ = (3⁻¹)² Step 3: Evaluate (1/3)² = 1/9 Answer: 1/9
Question 3: Simplify (4⁻²) × (2⁻³) Step 1: Use the product rule for exponents Step 2: (4⁻²) × (2⁻³) = (1/4²) × (1/2³) Step 3: Evaluate (1/16) × (1/8) = 1/128 Answer: 1/128

🧠 The One Thing Most Students Get Wrong

Most students get confused between the product rule and the quotient rule for exponents
The product rule states that aⁿ × aᵐ = aⁿ⁺ᵐ
The quotient rule states that aⁿ ÷ aᵐ = aⁿ⁻ᵐ
Make sure to use the correct rule for the given expression
