sum from n=1 to infinity of 5/(nsqrt(n))

n = 1 \sum \infty \frac{5}{n n}

converges

Solution steps

n = 1 \sum \infty \frac{5}{n n}

Apply the constant multiplication rule:

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

= 5 \cdot n = 1 \sum \infty \frac{1}{n n}

Simplify

n n : n^{\frac{3}{2}}

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

Apply p-Series Test:

converges

= 5 converges

= converges
