Let A = {0,1}, and consider A*, the set of all bitstrings. Let s,t E A*. Consider the relation R, where s Rt if and only if bitstring s is a prefix of bitstring t. For example, 00111 R 0011101 because all the bits in the first bitstring make up the first five bits in the second string: 0011101. Classify the following statement as true or false: The relation R is antisymmetric....

7. Consider the following proposition: For each integer a, a 2 (mod 8) if and only if (a2 + 4a): 4 (mod 8). (a) Write the proposition as the conjunction of two conditional statements (b) Determine if the two conditional statements in Part (a) are true or false. If a conditional statement is true, write a proof, and if it is false, provide a counterexample. (c) Is the given proposition true or false? Explain.

2. (a). Rewrite the following statement in equivalent if then form. Either 2021 is a prime or 2021 is a composite. (b). Rewrite the following universal statement in quantified if then form. For very integer n, 11 n is a necessary condition for 1001|n.
We know that we can reduce the base of an exponent modulo m: a(a mod m)k (mod m). But the same is not true of the exponent itself! That is, we cannot write aa mod m (mod m). This is easily seen to be false in general. Consider, for instance, that 210 mod 3 1 but 210 mod 3 mod 3 21 mod 3-2. The correct law for the exponent is more subtle. We will prove it in steps (a)...
