Suppose that pı, P2, ..., P, are the only primes congruent to 1 (mod 4). Prove that 4p?p, ... p, + 1 is divisible only by primes congruent to 3 (mod 4). Assuming that all odd prime factors of integers of the form x2 +1 are congruent to 1 (mod 4), use Exercise 6 to prove that there exist infinitely many primes congruent to 1 (mod 4).
21. An isolated prime is a prime number p such that neither p -2 nor p+2 is prime. For example, 47 is an isolated prime since 45 and 49 are both not primes. Write a computer program that finds all the isolated primes between 50 and 100. Do not use MATLAB's built-in function isprime. Matlab Instructions: Make in while and for, mode 21. An isolated prime is a prime number p such that neither p -2 nor p+2 is prime....
Suppose n ∈ ℤ. Let p1 , p2, …, pk be k different primes. Prove that n^2 is divisible by p1 p2 … pk if and only if n is divisible by p1, p2, … pk

Three charges: Q1, Q2, and Q3 are located on a straight line. The charge Q3 = 6.75e-6 C is movable along this line. The charges Q1 = -8.75e-6 C and Q2 = 2.80e-6 C are fixed at their positions, with Q2 at the distance d = 0.436 m to the right of Q1. For what position of Q3 (with respect to Q1) is the net force on Q3 - due to Q1 and Q2 - equal zero? Convention: use the...
Use Dirichlet’s Theorem on Primes in Arithmetic Progressions prove that there are infinitely many prime numbers whose base-8 representation ends in the digits (... 15)8.
Three charges, Q1, Q2 and Q3 are located on a straight line. The charge Q3 is located 0.125 m to the right of Q2. The charges Q1 = 1.73 μC and Q2 = -2.46 μC are fixed at their positions, distance 0.301 m apart, and the charge Q3 = 3.18 μC could be moved along the line. For what position of Q3 relative to Q1 is the net force on Q3 due to Q1 and Q2 zero? Give your answer...
