Father And Grandfather (Posted on 2003-04-02) Difficulty: 4 of 5
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).
