What examiners said

Finding the value of x was well answered by the majority of candidates. Common incorrect answers were 16 (√256), 4 (√256 ÷ 4) and 64 (256/4).

— Examiner report, October/November 2022, 0980/31 Q7(e)(ii) (Cambridge)

Nearly all candidates correctly identified 17 as the square root of 289. Occasionally a value was given that was not from the list. Answers were sometimes spoiled by candidates writing 17² and therefore not answering the question.

— Examiner report, October/November 2021, 0980/31 Q1(a)(i) (Cambridge)

Nearly all candidates demonstrated good use of their calculators to reach the correct answer. Occasional errors tended to be caused by misreading the number to be square rooted.
