Best ResponseYou've already chosen the best response.2\(\dfrac{1}{\sqrt1+\sqrt2}=\dfrac{\sqrt1\sqrt2}{1}=\sqrt2\sqrt1\) \(\dfrac{1}{\sqrt2+\sqrt3}=\dfrac{\sqrt2\sqrt3}{1}=\sqrt3\sqrt2\) ............................................................................................................ \(\dfrac{1}{\sqrt{99}+\sqrt{100}}=\dfrac{\sqrt{99}\sqrt{100}}{1}=\sqrt{100}\sqrt{99}\)  add them together \(\sqrt2\sqrt 1+(\sqrt3\sqrt2)+(\sqrt4\sqrt3)+..........+(\sqrt100\sqrt{99})\) open parentheses and cancel the like terms, you have \(\sqrt{100}\sqrt1=9\) right?
