Answer:

What is your question please tell me

Answer 2

Answer:

The inverse is [tex] /bar{2} [/tex]

Step-by-step explanation:

1) The Additive of integers modulo 6 has 6 elements namely,

$\bar{0},\bar{1},\bar{2},\bar{3},\bar{4},\bar{5}$

2) In this group, every element possesses a Additive inverse.

$in \: (Z_m,+_m) \: for \: all \: \bar{a} \: \: there \: exist \: \bar{m - a} \:$

which is its inverse as

Here a = 4 and m = 6

3) So the additive inverse of /bar{4} is /bar{2} in (Z_6,+_6)
