- C \(\frac{1}{\sqrt{2}}\)
- D \(\frac{1}{3 \sqrt{2}}\)
Answer & Solution
Correct Answer
(A) \(\frac{1}{4 \sqrt{2}}\)
Step-by-step Solution
Detailed explanation
\(\lim _{x \rightarrow 0} \frac{\sqrt{1+\sqrt{1+x^4}}-\sqrt{2+x^5+x^6}}{x^4}\) \(=\lim _{x \rightarrow 0} \frac{\left(\sqrt{1+x^4}-x^5-x^6-1\right)}{x^4\left(\sqrt{1+\sqrt{1+x^4}}+\sqrt{2+x^5+x^6}\right)}\)…
