SUMMARY
The limit of the expression $\lim_{n\rightarrow \infty }(2-2^{\frac{1}{n+1}})^{n}$ evaluates to $\frac{1}{2}$. The solution involves rewriting the limit as $L=e^{\lim_{n\rightarrow \infty }(n)(1-2^{\frac{1}{n+1}})$, leading to the logarithmic form $\ln(L)=\lim_{n\to\infty}\left(\frac{\ln\left(2-2^{\frac{1}{n+1}}\right)}{\dfrac{1}{n}}\right)$. Applying L'Hôpital's rule resolves the indeterminate form, confirming that $L=\frac{1}{2}$. The discussion also references the remarkable limit $\lim_{x\rightarrow 0}(1+x)^{\frac{1}{x}}=e$ as a potential method for solving similar limits.
