the second part of the question can be solved by the chineses
remainder theorem.
Problem 4 (4pts) Recalled Fermat's little theorem: For every p, a € N, if p is a prime and pla, then -I = 1 mod p. Use Fermat's little theorem to find a = 71002 mod 13) and b =(71002 mod 41). Find an 3 (0 < < 13 x 41) such that r = a (mod 13) and 2 = b (mod 41).
7. Use Fermat's Little Theorem to find the remainders of each of the division problems a. 6150 -19 b. 937531.
Discrete structures please help!! Use Fermat's little theorem to find the remainder when 91000 is divided by 13. To get credit, use Fermat's little theorem and show how each step is done without using a calculator.
Use the convolution theorem to find the inverse Laplace transform of the given function. 3 53 (82 +9) 7"{276900}09-0
1. (a) Use the Extended Euclidean Algorithmn to compute the inverse of 10 mod 17. (b) Use your answer from (a) so solve the equation 10x = 8 mod 17. (c) Compute 1616 mod 17. You may assume that Fermat’s Little Theorem is true.
Problem 1 Use the Chinese remainder theorem, find all integers x such that: (20 pts) x = 1 (mod 5) x = 2 (mod 7) x = 3 (mod 9) x = 4 (mod 11)
Problem 1 Use the Chinese remainder theorem, find all integers x such that: (20 pts) x = 1 (mod 5) r = 2 (mod 7) x = 3 (mod 9) I= 4 mod 11) Answer,
Problem 2. Find a primitive root for 53. Using this, you can
devise a bijection α from the integers modulo 52 to the nonzero
integers modulo 53 with the property that α(a + b) = α(a)· α(b)
modulo 53. Explain. Does the law of exponents get involved at all?
Note: For this to work right, you can think of integers mod 52 as
{0, 1, 2, . . . , 51} or as any complete system of residues modulo
52,...
2. Use modular arithmetic rules to find out the following: Use the rule: (a*b) mod x -( (a mod x) (b mod x)) modx Find out: (97)49 mod 119 Hints: 49 can be written as: 49-32 16+1 Try finding out 97 mod 119 Then, 972 mod 119, then 974 mod 119 etc.
