Let x>1x > 1 and for each positive integer nn, define
sn(x)=xx+1+x2(x+1)(x2+1)+x4(x+1)(x2+1)(x4+1)+⋯+x2−1(x+1)(x2+1)⋯(x26−1+1)\begin{aligned} s_n(x)= & \frac{x}{x+1}+\frac{x^2}{(x+1)\left(x^2+1\right)}+\frac{x^4}{(x+1)\left(x^2+1\right)\left(x^4+1\right)}+ \\ & \cdots+\frac{x^{2-1}}{(x+1)\left(x^2+1\right) \cdots\left(x^{2^{6-1}}+1\right)} \end{aligned}

Then lim⁡n→∞sn(x)\lim \limits_{{n \rightarrow \infty}} s_n(x) is equal to
View answer and explanation
Correct option: A
1
