Even/odd proofs: Practice problems Solutions

Since the sum of two odd numbers is even (by Problem 1), s+t = p2 is even. Hence p, must be even as well (by Problem 2). Therefore p = 2h for some h 2Z, by the de nition of an even integer. 2. Math 347 Worksheet on \Even/odd" Proofs Solutions A.J. Hildebrand

Next, we use the division algorithm to represent the given exponent 347 as a multiple of this (small) exponent we have found plus a remainder: 347 = 4 86 + 3: Finally, we use the properties of congruences and the fact that 34 1 mod 10 to nd the congruence sought: 3347 = 34 86+3 = (34)86 33 186 27 7 mod 10: Hence the last digit of 3347 in base ...
