Question: Exercise 1. Is x + 2 a prime number, where x is a positive integer? Exercise 2. Is x2 + 5x + 6 a prime number, where x is a positive integer? Exercise 3. Build the truth table of (-pVq) + (9-p), where p and q are two propositional formulae? Is the previous formula a tautology? Exercise 5 (Ex. 12, Chapter 1 of [Martin; 2011]).
Question: 2. Prime number Write a Python function that creates and returns a list of prime numbers between 2 and N, inclusive, sorted in increasing order. A prime number is a number that is divisible only by 1 and itself.
The definition of prime number is simple: A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself (wikipedia). For example, 2 is a prime number as it only has two divisors 1 and 2. 5 is also a prime number as it only has two divisors 1 and 5.
Prove that there exists an integer n such that n > 1 and n2 + 2n + 2 isa prime number Your solution’s ready to go! Enhanced with AI, our expert help has broken down your problem into an easy-to-learn solution you can count on.
Pass the number to a value-returning function that determines if the number is prime, and returns a boolean variable (true or false). The main routine will display a message indicating prime or not based on the true/false. If the number is 1, it's not considered prime. If the number is 2, it is prime. To check if any other entered number is ...
For each prime number p>2, state how many solutions x∈Z/p there are to the equation x(p2)+x=1modp, and justify your answer with a proof. Your solution’s ready to go! Our expert help has broken down your problem into an easy-to-learn solution you can count on.

Is the previous formula a tautology? - In each case below, say whether the given statement is true for the universe (0, 1)
(a) L = {an: n ≥ 2, is a prime number}. (b) L = {an: n is not a prime number}. (c) L = {an: n = k3 for some k ≥ 0}. (d) L = {an: n = 2k for some k ≥ 0}. (e) L = {an: n is the product of two prime numbers}. (f) L = {an: n is either prime or the product of two or more prime numbers}. (g) , where L is the language in part (a).
