lim┬(x→0)⁡〖3x/((√(9+x))-(√(9-x))).... Question from @meghaevilmagnae

IcukSugiarto $\lim_{x \to 0} \frac{3x}{ \sqrt{9+x}\,\,-\sqrt{9-x}}$

$= \lim_{x \to 0} \frac{3x}{ \sqrt{9+x}\,\,-\sqrt{9-x}} \times \frac{\sqrt{9+x}\,\,+\sqrt{9-x}}{\sqrt{9+x}\,\,+\sqrt{9-x}}$

$= \lim_{x \to 0} \frac{(3x)(\sqrt{9+x}\,\,+\sqrt{9-x})}{(9+x)\,\,-(9-x)}$

$= \lim_{x \to 0} \frac{(3x)(\sqrt{9+x}\,\,+\sqrt{9-x})}{9+x-9+x}$

$= \lim_{x \to 0} \frac{(3x)(\sqrt{9+x}\,\,+\sqrt{9-x})}{2x}$

$= \lim_{x \to 0} \frac{3(\sqrt{9+x}\,\,+\sqrt{9-x})}{2}$

$= \frac{3(\sqrt{9+0}\,\,+\sqrt{9-0})}{2}$

$= \frac{3(\sqrt{9}\,\,+\sqrt{9})}{2}$

$= \frac{3(3+3)}{2}$

$= \frac{3(6)}{2}$

$= \frac{18}{2}$

$= 9$
