Both my Father and my Father's Grandfather were born in years that can be expressed as [(m)^n - (n)^m], where 'm' and 'n' are both positive integers. In which years were they born ?
(Note: (a)^b implies: 'a' raised to the power of 'b', or 'a' multiplies 'b' number of times).
*** Year of birth of the father is 1927, as:
2^11 - 11^2 = 1927
*** Year of birth of the father's grandfather is 1844, as:
3^7 - 7^3 = 1844.
