- #1013 and 31 is a strange pair of numbers such that their squares 169 and 961 are also mirror images of each other. Find two more such pairs.Ans : (13)2 = 169 and (31)2 = 961
Similarly, two such numbers can be 12 and 21
∴ (12)2 = 144 and (21)2 = 441 and 102, 201
(102)2 = 102 × 102 = 10404
and (201)2 = 201 × 201 = 40401
