Question: Let a, b, c E Z. Which propositions are true? a. a = b (mod 5) = a mod b = 5 ba = b

Let a, b, c E Z. Which propositions are true? a.

Let a, b, c E Z. Which propositions are true? a. a = b (mod 5) = a mod b = 5 ba = b (mod 10) = 10a = b (mod 10) ca = b (mod 5) 5(a - b) d. 4 = 16 (mod 4) e. 11 = 101 (mod 10) a = b (mod 10) = 5a = 5b (mod 10) & a = b (mod 5) a mod 5 = b h. 2 = 10 (mod a) = 4 = 100 (mod a) Ci. 4 = 20 (mod 5) f
