limn(n+1n)n\lim_{n \to \infty} \left(\frac{n + 1}{n}\right)^{n}
Limit(((1 + n)/n)^n, n, oo, dir='-')
Detail solution
Let's take the limit
limn(n+1n)n\lim_{n \to \infty} \left(\frac{n + 1}{n}\right)^{n}
transform
limn(n+1n)n\lim_{n \to \infty} \left(\frac{n + 1}{n}\right)^{n}
=
limn(n+1n)n\lim_{n \to \infty} \left(\frac{n + 1}{n}\right)^{n}
=
limn(nn+1n)n\lim_{n \to \infty} \left(\frac{n}{n} + \frac{1}{n}\right)^{n}
=
limn(1+1n)n\lim_{n \to \infty} \left(1 + \frac{1}{n}\right)^{n}
=
do replacement
u=n1u = \frac{n}{1}
then
limn(1+1n)n\lim_{n \to \infty} \left(1 + \frac{1}{n}\right)^{n} =
=
limu(1+1u)u\lim_{u \to \infty} \left(1 + \frac{1}{u}\right)^{u}
=
limu(1+1u)u\lim_{u \to \infty} \left(1 + \frac{1}{u}\right)^{u}
=
((limu(1+1u)u))\left(\left(\lim_{u \to \infty} \left(1 + \frac{1}{u}\right)^{u}\right)\right)
The limit
limu(1+1u)u\lim_{u \to \infty} \left(1 + \frac{1}{u}\right)^{u}
is second remarkable limit, is equal to e ~ 2.718281828459045
then
((limu(1+1u)u))=e\left(\left(\lim_{u \to \infty} \left(1 + \frac{1}{u}\right)^{u}\right)\right) = e

The final answer:
limn(n+1n)n=e\lim_{n \to \infty} \left(\frac{n + 1}{n}\right)^{n} = e
Lopital's rule
There is no sense to apply Lopital's rule to this function since there is no indeterminateness of 0/0 or oo/oo type
