Best ResponseYou've already chosen the best response.1does it want you to apply a limit? or just simplify?

Best ResponseYou've already chosen the best response.1ok like before, multiply top and bottom by \(\Large \sqrt{x+h}+\sqrt{x}\) \[\Large \frac{\sqrt{x+h}\sqrt{x}}{h}\] \[\Large \frac{(\sqrt{x+h}\sqrt{x})}{h}\times \color{red}{\frac{(\sqrt{x+h}+\sqrt{x})}{(\sqrt{x+h}+\sqrt{x})}}\]

Best ResponseYou've already chosen the best response.0why isn't it multiplied by the bottom?

Best ResponseYou've already chosen the best response.1it is. I multiplied both top and bottom

Best ResponseYou've already chosen the best response.1Yes you're on the right track. One more step and you'll get `h` as the simplified result in the numerator \[\Large (\color{red}{a}\color{blue}{b})(\color{red}{a}+\color{blue}{b}) = \color{red}{a}^2  \color{blue}{b}^2\] \[\Large (\color{red}{\sqrt{x+h}}\color{blue}{\sqrt{x}})(\color{red}{\sqrt{x+h}}+\color{blue}{\sqrt{x}}) = (\color{red}{\sqrt{x+h}})^2  (\color{blue}{\sqrt{x}})^2\] \[\Large (\sqrt{x+h}\sqrt{x})(\sqrt{x+h}+\sqrt{x}) = x+h  x\] \[\Large (\sqrt{x+h}\sqrt{x})(\sqrt{x+h}+\sqrt{x}) = h\]

Best ResponseYou've already chosen the best response.1so we'll have \[\Large \frac{x+hx}{h(\sqrt{x+h}+\sqrt{x})}\] \[\Large \frac{h}{h(\sqrt{x+h}+\sqrt{x})}\] \[\Large \frac{\cancel{h}}{\cancel{h}(\sqrt{x+h}+\sqrt{x})}\] \[\Large \frac{1}{\sqrt{x+h}+\sqrt{x}}\]

Best ResponseYou've already chosen the best response.1I'm guessing it wants you to rationalize the denominator?

jim_thompson5910

Best ResponseYou've already chosen the best response.1then multiply top and bottom by the conjugate of the denominator

Best ResponseYou've already chosen the best response.0it doesn't specify all it says is simplify the radical expression
