Free practice quizzes › NAPLAN Numeracy Year 9 quiz › Indices & surds
In the Year 9 NAPLAN test, indices and surds is not labelled as such: it turns up inside multi-part items, tables and short scenarios. The questions here isolate the topic so a parent can see whether a low NAPLAN-style score comes from this content or from reading the question. Combine it with the full Year 9 NAPLAN practice quiz for the mixed experience.
Before the quiz, here is what the topic means at this level. Year 9 extends the index laws to negative and fractional indices, uses scientific notation for very large and small numbers, and introduces surds: simplifying, adding, multiplying and understanding why the square root of 2 is irrational.
Every question on this page was written to a specific Victorian Curriculum reference for Year 9 and checked by an RHZ tutor before it could be served.
Most errors in indices and surds are not random. When Year 9 students sit our Skills Check, the same handful of misunderstandings account for the majority of lost marks:
Each of these is fixable in a session or two once it has been named, which is why the results panel below shows the correct answer and an explanation rather than just a score.
Three things a parent or student can do this week:
For Years 7 to 10, practise the way a test is sat: mixed questions, time limits, full working. Then mark it honestly and re-do the errors.
The 10 questions are drawn from 14 eligible items on indices and surds in our Year 9 NAPLAN Numeracy bank, all at the easy and at-level tiers. The selection is fixed for this address so a shared link shows the same quiz; press New set of questions or add ?seed= to the address for a different mix. Options are shuffled, no two questions share a stem, and the answer key is fetched from our server only after you submit, so it is not hidden in the page.
Because every question here is on indices and surds, a low score is a clear signal and a high score is genuinely reassuring for this topic. What it cannot tell you is whether the other Year 9 NAPLAN Numeracy topics are equally secure, or how far above the year level the student can go; the free Skills Check covers both.
A one-page summary of indices and surds at Year 9 level, written by RHZ tutors to the Victorian Curriculum. Read it before the quiz, or print it for revision.
How to revise this: simplify a surd, check it on a calculator, and convert three numbers to and from scientific notation every session.

Yes, completely: no sign-up, no email, no payment, and you can take it as many times as you like. It is one of 3,261 free practice questions RHZ Tutoring publishes across Prep to Year 12. Press New set of questions, or add ?seed= to the address, for a different selection from the same topic.
Because a single-topic set is the most precise free check available: if the score is low, the gap is in indices and surds and nowhere else. There are 14 eligible questions on this topic in our Year 9 NAPLAN Numeracy bank, so several different sets are available before any repeat.
From RHZ Tutoring's own Year 9 NAPLAN Numeracy question bank, written to the Victorian Curriculum, checked by a tutor and passed through an automated quality gate. The same bank feeds our tutoring sessions and the free Skills Check. The questions on this page sit at the easy and at-level tiers.
Read the explanation for each incorrect answer first; most gaps in indices and surds are one of the misconceptions listed on this page. Then try a second set a few days later. If it is still low, the free Skills Check will show whether the gap is confined to this topic, and a tutor can build a short catch-up plan.
Yes. The Year 9 NAPLAN Numeracy quiz spreads ten questions across every topic for the year, and the hub lists topic quizzes for every year level from Prep to Year 12.
