sum from n=5 to infinity of (n!)/(n^n)

n = 5 \sum \infty \frac{n !}{n ^{n}}

converges

Solution steps

n = 5 \sum \infty \frac{n !}{n ^{n}}

Apply Series Ratio Test:

converges

= converges

\int \frac{1}{- t ^{2} + 6 t - 8} d t

\frac{d}{d x} (0.006 x^{3} + 0.02 x^{2} + 0.5 x)

\frac{d}{d y} (y cos (x) y)

3 x^{2} - 9

y^{^{'}} = \frac{e ^{x}}{y ^{2}}
