Please show that in any monoid (semigroup with neutral element e) if some element a has inverse a^-1, this inverse is unique. This means no element can have more than one inverse. [Hint: Start from writing the definition of the inverse for element a. Consider an element a which has two inverses (a1)^-1 and (a2)^-1. Then think about the value of (a1)^-1a(a2)^-1]. Comment: This is about any monoid which has inverses for some elements, but not necessarily for all elements....
