    This is the last time I leave my work til the night before it is due in.

    Does 1/(1-[1/q]) simplify to 1/q - 1? It would really help me if it did but for some reason I don't really know what to do with it! If it doesn't I have gone wrong somewhere else in the question

    Thanks.

    No it doesn't. Do it like this

    \displaystyle \frac{1}{1 - \frac{1}{q}} = \frac{q}{q(1 - \frac{1}{q})}

    (they're equal because I've multiplied the numerator and denominator both by q, so the fraction overall remains unchanged)

    Now expand out and simplify.

    Thanks for the response. I've worked out what I did wrong. I was meant to be working with powers, and treated them just as numbers.
