What is the square root of 676?
- 23
- 26
- 28
- 36
Answer and explanation
Correct answer: B - 26
26 × 26 = 676, so the square root of 676 is 26. A quick check: 676 ends in 6, so its root ends in 4 or 6, and since 25² = 625 and 27² = 729 the root lies between 25 and 27. 23² = 529, 28² = 784 and 36² = 1296 are all wrong.
