Question

If m, n ∈ I₀ and $f\left\lbrack \frac{2x}{1 + x^{2}} \right\rbrack\lbrack f(x)\rbrack^{2}$= some integer then value of this limit is

• A. 3
• B. 2
• C. $\lbrack f(x)\rbrack^{3}$
• D. None of these

Answer 1

Answer: (A)

3

Answer 2

$\lim _ { x \rightarrow 0 }$= I

⇒ $\lim _ { x \rightarrow 0 }$= I

⇒ $\lim _ { x \rightarrow 0 }$= I

⇒ n = 2 and value = = 3
