Answer the following questions using modular arithmetic a) Determine if 5201,001 −2 is divisible by 3....
please answer all the questions. just rearranging. Explanation is not needed. Use modular arithmetic to prove that 3|(221 – 1) for an integer n > 0. Hence, 3|(221 – 1) for n > 0. To show that 3|(221 – 1), we can show that (221 – 1) = 0 (mod 3). We have: (221 – 1) = (4” – 1) (mod 3) Then, (22n – 1) = (1 - 1) = 0 (mod 3) Since 4 = 1 (mod 3),...
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.
Question Lisiaiq a modular arithmetic Compute the following a) –3 mod 5; 9' mad 26; 2t med 9; 8t med 13 6) Find X (smallest) from 9 = 2* (med 11)
Modular arithmetic topic: 97=2 mod 5 and 144=4 mod 5. Hence (97^3+144^2=2^3+4^2=8+16) . so the conclusion is 97^3+144^2=4 mod 5(this is the answer but I have no idea) . I don't quite understand here......

Compute the value of the following modular expression using modulo reduction. Your answer must be a specific mod 13 number, not a formula or expression of any kind. Show your work. 7^(17) mod 13 =
1. [10 marks] Modular Arithmetic. The Quotient-Remainder theorem states that given any integer n and a positive integer d there exist unique integers q and r such that n = dq + r and 0 r< d. We define the mod function as follows: (, r r>n = qd+r^0<r< d) Vn,d E Z d0 Z n mod d That is, n mod d is the remainder of n after division by d (a) Translate the following statement into predicate logic:...
