Index laws, negative exponents and SI prefixes
Use exponent laws carefully with constants, variables and powers of 10.
SkillrHub quiz practice is built for curriculum-aligned revision with answer feedback and a clear review path.
60-second Quick Read
- Negative powers represent reciprocals: a⁻³ = 1/a³ when a ≠ 0.
- For the same base, multiply by adding exponents and divide by subtracting exponents.
- Common trap: Apply an outside power to every factor, including coefficients and variables.

Use this short shuffled test set to check the skill, read feedback and review missed items. Repeat quiz practice to access more of the full question bank over time.
- Worked example: Before answering, classify what the question gives, what it asks for, and which curriculum idea links them. For Index laws, negative exponents and SI prefixes, explain the evidence or method in one complete sentence before selecting the final answer.
- Common mistake: Do not match answers by familiar wording only. Check the full AC9M9A01 idea, the units or evidence, and any exception in the stem.
- Assessment guidance: Use this short shuffled set for one attempt. Repeat quiz practice to get access to more of the full question bank over time.
- SkillrHub review path: Use feedback to name the misconception, practise a corrected example, and retest only after you can justify the answer aloud.
