11*11 = 121 & 11*11 = 121
12*12 = 144 & 21*21 = 441
13*13 = 169 & 31*31 = 961
22*22= 484 & 22*22 = 484

P.S: Had to use C program to figure this out !

What is the number if it divides exactly by 13 and when you write its digits in reverse order you make a square number. (You get a square number when you multiply a number by itself - 64 is square because it is 8 times 8)

23 x 64 gives the same answer as 46 x 32 (everything written in reverse order) can you find other pairs of two digit numbers with different digits that work like this?
