    Pf, at least make the result pretty Felix:

    \sqrt{\dfrac{1}{\phi^2}+ \sqrt{\dfrac{1}{\phi^4}+ \sqrt{\dfrac{1}{\phi^8}+\cdots}}  }

    ... or something
    What the hell does that mean?

    Let me try. Series is 10^{\frac{1}{2}}+10^{\frac{1}{4}  }+10^{\frac{1}{8}}+... 10^{\dfrac{1}{2n^3}} It's a geometric series with a=\sqrt{10} and r=10^\frac{1}{4} S_{\infty}=\dfrac{a}{1-r} so \frac{\sqrt{10}}{1-10^\frac{-1}{4}}

    Don't panic! \phi is just the golden ratio. I simply amended Felix's question so that it would yield a cleaner result.

    I know what the symbol meant by why did you did you inverse it?

    I still can't see a way of getting an answer as I'm not accustomed to these types of questions and haven't had much practice with them :-/

    If this is from C2 then I've clearly forgotten the content.

    Oh. Not from C2, just when I was doing some extra maths with some mates awhile ago. I came across the first example and understood the concept. Now. I'm just painfully lost.

    Do we get the ratio by doing  \frac{10^\frac{1}{4}}{10^\frac{1  }{2}}?

    I'm probably not the guy to ask this time Didn't even the get the first one. I understood how from the hint, but not how he got from the series to the hint.
