How to prove (1,1) has largest order in direct product Zn1+Zn2

[@MathematicalScience]

Just find the order of (a,b)

[@ChanneLOL]

I am confused

[@sneha_truffles]

Q no 36 ?? .... I think here no cyclic subgroup of order 9 in z 12 + z4 + z15.... But non cyclic subgroup of orfer 9 we can find..... ... Tell me is fine or not???

[@MathematicalScience]

YES, CORRECT

[@noindamster3581]

In Q. 30 there are only 7 subgroups that i could find...

[@noindamster3581]

Sir In Q. 36 don't think there exist an element of order 9

[@sneha_truffles]

Here there s no cyclic subgroup of order 9 but non cyclic subgroup of oreder 9 , ..... We can find.... Order 1 or order 3 ke elemnts .....

[@ayankamran6277]

Plz q 14 bjdy

[@MathematicalScience]

because EDP of such subgroups is Abelian but Dn is non-Abelian for n>=3
