Homework Set 3
Due: February 21 at the beginning of class
Collaboration in groups is ok, even encouraged. However, each of you must turn in a separate writeup. (But please do indicate with whom you collaborated to make life easier for the grader.)
Section 2.1: 6b, 10abc, 12bde, 13b, 14a (do formally) (tricky, save for last) (Hint: write as ((2^k)^2-1^2), read the Wikipedia article about Mersenne Primes for more)
Section 2.2: 3bdf, 4abc, 17, 19.
12bd were already on HW2, so no need to redo them.
