    Can anyone give me help these questions please:

    prove there are no integers n, n>1 for which n divides into 2^n-1.
    prove there exists infinite integers n such than n divides into 2^n+1.
    which natural no. can be expressed in the form 1=p1 +p1p2... p1p2...pk.
    show that if we take n+1 natural no. from the set (1,2....2n) we have taken 2 relatively prime numbers.
