question

For every positive real number xx, let g(x)=limr→0((x+1)r+1−xr+1)1/rg(x)=\lim _{r \rightarrow 0}((x+1)^{r+1}-x^{r+1})^{1/r}. What is the limit of g(x)/xg(x)/x as xx goes to infinity?
Plain-text mathematical notation (without MathML)
For every positive real number x, let g(x)=lim_(r→0)((x+1)^(r+1)−x^(r+1))^(1/r). What is the limit of g(x)/x as x goes to infinity?
Original LaTeX notation
For every positive real number $x$, let $g(x)=\lim _{r \rightarrow 0}((x+1)^{r+1}-x^{r+1})^{1/r}$. What is the limit of $g(x)/x$ as $x$ goes to infinity?
