(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

(ab)[itex]^{n}[/itex]= a[itex]^{n}[/itex]b[itex]^{n}[/itex] for any 3 consecutive numbers n [itex]\in[/itex]N

2. Relevant equations

for an abelian group G, ab=ba [itex]\forall[/itex]a,b[itex]\in[/itex]G

if a[itex]\in[/itex]G, a has an inverse element also [itex]\in[/itex]G such that aa[itex]^{-1}[/itex] = e

3. The attempt at a solution

doesnt look right but heres the attempt
