1. ## 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:

$
\sqrt[3]{e^{2\pi}}+\sum_{n=1}^{\infty}\frac{1}{2^{n}}
$

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! 2.

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

(the infinite sum is just 1)
