    thanks so much ... now i get it :)

    Undergrad Does n Divide (n-1)! for Composite and Prime Numbers?

    can u help me with this question If n ≥ 6 is a composite integer, then n |(n − 1)! If n is a prime number, then n does not divide (n−1)!

    Undergrad If a,m and n are positive integers with m<n

    well this is the question... if a,m and n are positive integers with m<n, then (a^(2^m)+1) is a divisor of (a^(2^n)-1)... I started using induction and it works for the first step... but for the second one i do not know if i can make induction on m... any hint would help.. thanks :)
