3.观察下列各式,通过分母有理化,把不是最简二次根式的化成最简二次根式:
$\frac{1}{\sqrt{2}+1}$=$\frac{1×(\sqrt{2}-1)}{(\sqrt{2}+1)(\sqrt{2}-1)}$=$\frac{\sqrt{2}-1}{2-1}$=$\sqrt{2}$-1,
$\frac{1}{\sqrt{3}+\sqrt{2}}$=$\frac{1×(\sqrt{3}-\sqrt{2})}{(\sqrt{3}+\sqrt{2})(\sqrt{3}-\sqrt{2})}$=$\frac{\sqrt{3}-\sqrt{2}}{3-2}$=$\sqrt{3}$-$\sqrt{2}$,
同理可得:$\frac{1}{2-\sqrt{3}}$=2-$\sqrt{3}$,…
从计算结果中找出规律,并利用这一规律计算
($\frac{1}{\sqrt{2}+1}$+$\frac{1}{\sqrt{3}+\sqrt{2}}$+…+$\frac{1}{\sqrt{2009}+\sqrt{2008}}$)($\sqrt{2009}$+1)的值.
