(D) લક્ષ $\lim _{x ightarrow a} \frac{\sqrt{a+2 x}-\sqrt{3 a}}{\sqrt{x}-\sqrt{a}}$ ની કિંમત શોધવા માટે,આપણે અંશ અને છેદનું સંમેયીકરણ કરીએ: $\lim _{x}$ ${ightarrow a} \frac{\sqrt{a+2 x}-\sqrt{3 a}}{\sqrt{x}-\sqrt{a}} 	imes \frac{\sqrt{x}+\sqrt{a}}{\sqrt{x}+\sqrt{a}} 	imes \frac{\sqrt{a+2 x}+\sqrt{3 a}}{\sqrt{a+2 x}+\sqrt{3 a}}$ $= \lim _{x ightarrow a} \frac{(a+2x) - 3a}{x-a} 	imes \frac{\sqrt{x}+\sqrt{a}}{\sqrt{a+2x}+\sqrt{3a}}$ $= \lim _{x ightarrow a} \frac{2x - 2a}{x-a} 	imes \frac{\sqrt{x}+\sqrt{a}}{\sqrt{a+2x}+\sqrt{3a}}$ $= \lim _{x ightarrow a} \frac{2(x-a)}{x-a} 	imes \frac{\sqrt{x}+\sqrt{a}}{\sqrt{a+2x}+\sqrt{3a}}$ $= 2 	imes \frac{\sqrt{a}+\sqrt{a}}{\sqrt{a+2a}+\sqrt{3a}} = 2 	imes \frac{2\sqrt{a}}{\sqrt{3a}+\sqrt{3a}} = 2 	imes \frac{2\sqrt{a}}{2\sqrt{3a}} = \frac{2}{\sqrt{3}}$

$\lim _{x \rightarrow a} \frac{\sqrt{a+2 x}-\sqrt{3 a}}{\sqrt{x}-\sqrt{a}} = $
