Ten-thousands Digit Determination (Posted on 2023-08-06) Difficulty: 3 of 5
Determine the ten-thousands digit of N, where:

N = 55555

*** Computer program assisted solutions are welcome, but a semi-analytic (hand calculator and p&p method) is preferred.
*** N is equal to 5^(5^5^5^5) and NOT equal to (((5^5)^5)^5)^5).
