Interesting fact ---> Question of the day

Question of the day - which number we are referring to here

1. Its a perfect square (3 digit number - XYZ)
2. It has 2 more anagrams which are perfect square
3. Insert a number as its second digit - And you get a perfect cube! (XAYZ)
4. Anagrams of XAYZ - Two of them again - They are also perfect square!

Interesting facts ---> 26 - Number in Focus - 3136

Some facts about the number 3136

1. Add 31 + 36 = 67, Subtract 36 - 31 = 5. Multiple 67 * 5 = 335. Now Add 3 + 3 = 6. Prefix 5 before that and you get 56 which is the Square root of 3136!

2. 3136 - Anagram is 3136 - Again one of the few numbers which has this pattern like 65536

3. Add 3+1 = 4. Add 3 + 6 = 9. Now add 4 + 9 = 13. Multiple 4 * 9 = 36. Now closely look at the original number 3136 - you will find 36 and 13 :)

4. Now take 56 which is the Square root of 3136. 56 + 5 + 6 = 67 which is sum of 31 + 36!
