(B) અમે લક્ષની કિંમત શોધીએ: $\lim _{x \rightarrow \infty} x^3 \left(\sqrt{x^2+\sqrt{1+x^4}}-x \sqrt{2}\right)$ પદનું સંમેયીકરણ કરતા: $= \lim _{x \rightarrow \infty} \frac{x^3 \left(x^2+\sqrt{1+x^4}-2 x^2\right)}{\sqrt{x^2+\sqrt{1+x^4}}+x \sqrt{2}} = \lim _{x \rightarrow \infty} \frac{x^3 \left(\sqrt{1+x^4}-x^2\right)}{\sqrt{x^2+\sqrt{1+x^4}}+x \sqrt{2}}$ અંશનું ફરીથી સંમેયીકરણ કરતા: $= \lim _{x \rightarrow \infty} \frac{x^3 \left(1+x^4-x^4\right)}{\left(\sqrt{x^2+\sqrt{1+x^4}}+x \sqrt{2}\right) \left(\sqrt{1+x^4}+x^2\right)}$ છેદમાં $x^3$ વડે ભાગતા: $= \lim _{x \rightarrow \infty} \frac{x^3}{x \left(\sqrt{1+\sqrt{\frac{1}{x^4}+1}}+\sqrt{2}\right) \cdot x^2 \left(\sqrt{\frac{1}{x^4}+1}+1\right)}$ $= \lim _{x \rightarrow \infty} \frac{1}{\left(\sqrt{1+\sqrt{\frac{1}{x^4}+1}}+\sqrt{2}\right) \left(\sqrt{\frac{1}{x^4}+1}+1\right)}$ $x \rightarrow \infty$ મુકતા: $= \frac{1}{(\sqrt{1+1}+\sqrt{2})(1+1)} = \frac{1}{(\sqrt{2}+\sqrt{2})(2)} = \frac{1}{2 \sqrt{2} \cdot 2} = \frac{1}{4 \sqrt{2}}$

$\lim _{x \rightarrow \infty} x^3 \left\{\sqrt{x^2+\sqrt{1+x^4}}-x \sqrt{2}\right\} = $
