Algebraic Structures (Groups,Rings and Fields)


Answer TRUE or FALSE for the FOLLOWING

  1. The law of internal composition a◦b= a + 2b is a Group
  2. The law of internal composition a◦b=(a+b)/2 is a Group.
  3. The law of internal composition a◦b = a + b-1 is an Abelian Group
  4. The law of internal composition a◦b = ab2 is an Abelian Group
  5. The law of internal composition a◦b = (a + b) / 2 and the law a◦b = a + 2b is a Ring
  6. The law of internal composition (a, b) ◦ (c, d) = (a + c, b + d) and the law
    (a, b) ◦ (c, d) = (ac, 0) is a Ring
  7. The law of internal composition a◦b = a + b-1 and the law a◦b = a + b-ab is a Ring
  8. The law of internal composition a◦b = a + b-1 and the law a◦b = a + 2b is a Field
  9. The law of internal composition (a, b) ◦ (c, d) = (a + c, b + d) and the law
    (a, b) ◦ [(c, d) ◦ (e, f)]) = (ace, bdf) is a Field
