usually by identity it means, multiplication :


11a = a

Answer 6

oh

Answer 7

not sure, not good with group theory

Answer 8

then also
\(Z_{11} ^×\)
work

Answer 9

wait no , not sure forget it

Answer 10

wait , this could be yeah

\(Z_{10} ^\times \)
right ?

Answer 11

it works i guess cuz 11a = a mod 10

Answer 12

\(Z_{10} \)={0,1,2,3,4,5,6,7,8,9}

11 mod 10=1

Answer 13

ohkk , hae you ever deal with something like this but not in residues rings ?
