sum from n=1 to infinity of 5/(n^2+n^3)

n = 1 \sum \infty \frac{5}{n ^{2} + n ^{3}}

converges

Solution steps

n = 1 \sum \infty \frac{5}{n ^{2} + n ^{3}}

Apply the constant multiplication rule:

\sum c \cdot a_{n} = c \cdot \sum a_{n}

= 5 \cdot n = 1 \sum \infty \frac{1}{n ^{2} + n ^{3}}

Apply Series Comparison Test:

converges

= 5 converges

= converges

n = 0 \sum \infty e^{- 1 n}

n = 1 \sum \infty \frac{2 n}{7 n - 6}

n = 1 \sum \infty n + 3

n = 0 \sum \infty \frac{7}{5 n + 4}

n = 1 \sum \infty 5 (\frac{1}{3})^{n - 1}
