Question: let be a binary operation on a set s...

Question details

Let * be a binary operation on a set S. Assume the domain of definition of * is S^2. Assume * is associative and n is the neutral element for *. Now, let s and t be two elements of S. We say that t is a left inverse of s under * iff t*s = n. We say that t is a right inverse of s iff s*t = n. Show that if an element of S has both a Left inverse and a right inverse under * then left inverse and right inverse are equal.2. Let ★ be a binary operation on a set S. Assume the domain of definition of * is S, assume ★ is associative and n is the ne
