Advertisement
Answer and explanation
Correct answer: 2809
The square of a number is obtained by multiplying it by itself. Thus, \(53^2=53\times53=2809\). Therefore, 2809 is correct. Although 2709 may look close, it is not obtained on multiplication. Exam tip: use \((50+3)^2=50^2+2\times50\times3+3^2\), which gives \(2500+300+9=2809\).
