is means if its finite there exist an integer n s.t. ab^n =e but if else ; ther exest no integer s.t. ab^n =e now we can write ab = a(ba)a^-1 then ...compleate

it means a^n=e where n is the least integer satsfy last equations

for that question i have a hent which is (( write ab=a(ba)a^-1)))

NOW, o(a) means order of element a a is element in group G

very important... at any group G show i)o(ab) = o(ba) ii) o(a) = o(cac^-1) c in G please i want solving

mr NoMoreExams these question i want to solve it for my homework and for my searching ... its very important for me

Q4) LET G is abilian of order pq , with g.c.d (p,q)=1 , assume there exist a,b in G and o(a)= p,o(b) = q show that G is cyclic

Q3)if Gis afinite group of even order, then G contains an element (a) not equal zero s.t. a^2= e

now, how to proof that if G is group then o(ab) = o(ba) o(cac^-1) =o(a) for all a,b,c in G note that G not abelian??

first qustion i don't understand it?

please clearlly more i don't under stand

q1) write out an additiontable for Z2 \oplusZ2 Q2)if a^2=e \forall a in G then g is abelian (solve)

mr sutupidmath ... czn u say my proof for 2 pf: since x non zerc, so x either rational or irrational i. if x rational & x non zero... x =p\q wher p,q is intger... y is irrational. now suppose x\y is rastional x\y=r\s...r,s is integer. x\y=(p\q)\y=r\s y=(s\r)*(p\q)...which is...

what it mean? please & where num 2 proof please hashim thanks

mr GIb Z i don't understand proof? please hellp me?? hashim Edit: hashim, you have been warned several times to stop with the obnoxious formatting.
