    Limit Help

    How do I take this limit?

    Limit as x approaches 1 of \frac{x^p - 1}{x^q - 1}

    Are p and q meant to be positive integers? Then use the fact that x^n - 1 = (x - 1)(1 + x + x^2 + ..... + x^{n-1}).

    Alternatively, it's an obvious candidate for applying l'Hospital's Rule.
