Writing √3 - 1 to create an equation for √3

[flying2000]

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?
Any hints appreciated..

thanx

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

So $\frac{1}{\sqrt{3}} = ?$

Try multiplying the top and bottom by $\sqrt{3}$

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..
