Consider an exponential tower of three thousand 7's.(adsbygoogle = window.adsbygoogle || []).push({});

What is the remainder when you divide the tower by 11?

Note that this notation means 7^(7^7) not (7^7)^7. So it's kinda like the Ackermann Function maybe?

The final answer must be given as a single integer in the range 0-10.

Anyone got any ideas???
