    Check please! (pun intended)

    So, my brother-in-law says I owe him money for our last round of beers, and he's a sporting kind of guy, so I wrote him a check and put this in the amount line:

    <br />
\sqrt[3]{e^{2\pi}}+\sum_{n=1}^{\infty}\frac{1}{2^{n}}<br />

    My calculations show this to be a check for $9.12. I just wanted to get someone to check my calculation before I give it to him (not that a bank will ever cash it for him - and if they do, hopefully they get it right!).

    Thanks!

    Yes, it is 9.12 (maxima gives 9.120527396669775) ^^

    (the infinite sum is just 1)
