sum from n=1 to infinity of 9/(5n^3)

n = 1 \sum \infty \frac{9}{5 n ^{3}}

converges

Solution steps

n = 1 \sum \infty \frac{9}{5 n ^{3}}

Apply the constant multiplication rule:

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

= \frac{9}{5} \cdot n = 1 \sum \infty \frac{1}{n ^{3}}

Apply p-Series Test:

converges

= \frac{9}{5} converges

= converges

n = 0 \sum \infty \frac{n}{1}

n = 0 \sum \infty \frac{4}{n}

n = 1 \sum \infty \frac{2}{n ^{0.45}}

n = 0 \sum \infty \frac{n}{10 n ^{6} + 1}

n = 0 \sum \infty \frac{3}{2 ^{n - 1}}
