Question

Match the following numbers with their squares.

• A. 361
• B. 529
• C. 256
• D. 625

Answer 1

$($16${)}^2$ = 256

$($19${)}^2$ = 361

$($23${)}^2$ = 529

$($25${)}^2$ = 625

Alternative method:

Arrange the numbers in ascending order.

16 $<$ 19 $<$ 23 $<$ 25

So, the squares must be in ascending order, arrange the squares in ascending order.

256 $<$ 361 $<$ 529 $<$ 625
