    Standard limit proof

    For any x > 0, we have lim n-->infinity of x^1/n = 1

    Hint: Treat cases x >= 1 and x < 1 separately. You might wish to first use the following to prove the preliminary result that for every epsilon > 0, and every real number M > 0, there exists an n such that M^1/n <= 1+epsilson:

    "Let x be a real number. Then the limit lim n-->infinity of x^n exists and is equal to zero when the absolute value of x < 1, exists and is equal to 1 when x=1, and diverges when x= -1 of when absolute value of x > 1."
