(C) લક્ષ $\lim _{x ightarrow 8} \frac{\sqrt{1+\sqrt{1+x}}-2}{x-8}$ ની ગણતરી કરવા માટે,અંશનું સંમેયીકરણ કરતા:$\lim _{x ightarrow 8} \frac{\sqrt{1+\sqrt{1+x}}-2}{x-8} 	imes \frac{\sqrt{1+\sqrt{1+x}}+2}{\sqrt{1+\sqrt{1+x}}+2}$$= \lim _{x ightarrow 8} \frac{1+\sqrt{1+x}-4}{(x-8)(\sqrt{1+\sqrt{1+x}}+2)}$$= \lim _{x ightarrow 8} \frac{\sqrt{1+x}-3}{(x-8)(\sqrt{1+\sqrt{1+x}}+2)}$હવે,બાકી રહેલા પદનું સંમેયીકરણ કરતા:$= \lim _{x ightarrow 8} \frac{\sqrt{1+x}-3}{(x-8)(\sqrt{1+\sqrt{1+x}}+2)} 	imes \frac{\sqrt{1+x}+3}{\sqrt{1+x}+3}$$= \lim _{x ightarrow 8} \frac{1+x-9}{(x-8)(\sqrt{1+\sqrt{1+x}}+2)(\sqrt{1+x}+3)}$$= \lim _{x ightarrow 8} \frac{x-8}{(x-8)(\sqrt{1+\sqrt{1+x}}+2)(\sqrt{1+x}+3)}$$= \lim _{x ightarrow 8} \frac{1}{(\sqrt{1+\sqrt{1+x}}+2)(\sqrt{1+x}+3)}$$x = 8$ મુકતા:$= \frac{1}{(\sqrt{1+\sqrt{9}}+2)(\sqrt{9}+3)}$$= \frac{1}{(\sqrt{1+3}+2)(3+3)}$$= \frac{1}{(2+2)(6)} = \frac{1}{4 	imes 6} = \frac{1}{24}$
