What is the value of (59^2)?
Answer and explanation
Correct answer: 3481
\(59^2\) means \(59 \times 59\). Using \((60-1)^2 = 60^2 - 2\times60\times1 + 1^2 = 3600 - 120 + 1 = 3481\), the correct value is 3481. A value such as 3581 results from not applying the subtraction term correctly. Exam tip: For numbers close to 60, use \((a-b)^2\) to find the square quickly.
