Interesting Facts ----> 41 - Speciality of 1681

Let's look at the number 1681

- It is 41 * 41 (just  coincidence that my Blog series is also 41 :))
- Now split 1681 into two parts - 16 and 81
- 16 is 4 * 4 and 81 is 9 * 9
- Drilling down further... 4 is again 2 * 2 and 9 is 3 * 3

Net-Net this is how it looks

Row 1 ---  1681
Row 2 ---    4  9   (Square root of 16 and 81)
Row 3 ---    2  3   (Square root of 4 and 9)

Now look further....

Look at the number in the second row - 49.

Square of 49 is 2401. Again if you subtract the digits 24 and 01 you get 23 which is the 3rd row in the above series :)
