## January 2017 Fiendish Function

The Fiendish Function posed during January 2017 had the following sample guesses and replies:

- 1
- 2
- 2
- 16
- 3
- 512
- 4
- 66
- 5
- 36
- 10
- 4

The rule was: "Square the number, then add 2 to the power of the digits together".

Suppose the guess was 12:

- Square the number, giving 144.
- Take the number's digits, giving 1, 4, 4
- Take 2 to the power of each digit, giving 2, 16, 16
- Add these together, giving 34.

So the result is 34.
