sum from n=1 to infinity of 1/(n^{4/5)}

n = 1 \sum \infty \frac{1}{n ^{\frac{4}{5}}}

diverges

Solution steps

n = 1 \sum \infty \frac{1}{n ^{\frac{4}{5}}}

Apply exponent rule:

\frac{1}{a ^{b}} = a^{- b}

\frac{1}{n ^{\frac{4}{5}}} = n^{- \frac{4}{5}}

= n = 1 \sum \infty n^{- \frac{4}{5}}

Apply Series Integral Test:

diverges

= diverges
