Nope. Test is 6pm my time, so I'm just tying up a few loose ends.

You've probably already had your test, but everything you have done so far is correct. Now you just need to show that 1 + l(2^{k + 3}) + l^{2}(2^{2k + 4}) is congruent to 1 (mod 2^{k + 3}), which it is as far as I can tell...

How is : 1 + l(2
^{k + 3}) + l
^{2}(2
^{2k + 4}) congruent to 1 (mod 2
^{k + 3})?
i tried breaking it up: 1 + l(2
^{k + 3}) + l
^{2}(2
^{k + 2})
^{2}......so it's this last term that's giving me a problem. I also had one other short question if you don't mind?
