In exercises 7 through 10, compute the indicated quantities for the given homomorphism o 7 ker(o) and o(25) for o: z+z1 such that ø(1)=4. 8 ker(ø) and 38) for : z z such that ø1)= 6 9 ker(o) and 7) for : zoz such that o1) 12 10 ker(6) and o(5,7) for : z x zzx z such that o1,0)= (3,5) and (0, 1)= (-2,4). 11 let g be a group, and let ge g. let o, : g+g be defined by o(t) = grg"1 for z € g. for which g e g is o, a homomorphism?
