78 CHAPTER 5. THE CHINESE REMAINDER THEOREM 6. (a) Let m mi,m2 Then r a (mod mi), ag (mod m2) can be solved if and only if (m, m2) | a1-a2. The solution, when it exists, is unique modulo m. (b) Using part (a) prove the Chinese remainder theorem by induction. 7. There is a number. It has no remainder...
Problem 2.6.1. We have 7*6* 55 = 2310. Extend the technique of the Chinese remainder theorem to find the solutions in Z2310 of the equations. 2x => 3 X 564 5x 355 50 Hint: There will be 5 solutions because the last equation has 5 solutions. You may use the Mathematica command ExtendedGCD.

In addition, prove that any two solutions of the system are congruent modulo InJ b. c. Let I and J be ideals in...
6.32 Theorem. If k and n are natural numbers with (k, d(n)) =I, then there exist positive integers u and v satisfving ku=(n)u The previous theorem not only asserts that an appropriate exponent is always availahle, but it also tells us how to find it. The numbers u and are solutions lo a lincar Diophantine cquation just like those we studied in Chapter 6.33 Exercisc. Use your observations so far to find solutions to the follow ing congruences. Be sure...
