5.观察下列等式:$\frac{1}{\sqrt{2}+1}$=$\frac{\sqrt{2}-1}{(\sqrt{2}+1)(\sqrt{2}-1)}$=$\sqrt{2}$-1
$\frac{1}{\sqrt{3}+\sqrt{2}}$=$\frac{\sqrt{3}-\sqrt{2}}{(\sqrt{3}+\sqrt{2})(\sqrt{3}-\sqrt{2})}$=$\sqrt{3}$-$\sqrt{2}$
$\frac{1}{\sqrt{4}+\sqrt{3}}$=$\frac{\sqrt{4}-\sqrt{3}}{(\sqrt{4}+\sqrt{3})(\sqrt{4}-\sqrt{3})}$=$\sqrt{4}$-$\sqrt{3}$;…
回答下列问题:
(1)利用你观察到的规律,化简:$\frac{1}{3\sqrt{2}-\sqrt{17}}$;
(2)计算:$\frac{1}{1+\sqrt{2}}$+$\frac{1}{\sqrt{2}+\sqrt{3}}$+$\frac{1}{\sqrt{3}+2}$+$\frac{1}{2+\sqrt{5}}$+…+$\frac{1}{\sqrt{2015}+\sqrt{2016}}$.
