OK, so you can't solve this. What have you tried? Where are you stuck? We are willing to help but we need to know what you need help with.hi guys, i can´t solve this, for what values from \(\displaystyle a\) is this serie convergent?
\(\displaystyle a \epsilon R\) (is a constant)
\(\displaystyle
\sum_{n=1}^{\infty} \sqrt[]{n+a} - \sqrt[4]{n^2+2n}
=
\)
