    Q: write roo(3)-1 in another way,and use this to produce a non-trivial equation for root(3) in terms of itself..

    I don't ever know what it means?

    So [itex]\frac{1}{\sqrt{3}} = ?[/itex]

    Try multiplying the top and bottom by [itex]\sqrt{3}[/itex]

    Other than that, I am not sure what the question would be asking.

    The following is the rest of the whole question..

    1)write root(3)-1 in another way,and use this to produce a non-trivial equation for root(3) in terms of itself

    2)suppose m,n(m,n is natural numbers) are such that m/n=root(3),use (1) to write root(3)as another combination of m and n.
    3)use (2) to show that root(3) in not rational.

    Any hints appreciated..
