Question

multiplicative inverse of real number is unique.proof?

Answer 1

Therefore, x = y = z − 1 , and thus, there really is only one multiplicative inverse of that is, the inverse of a given complex must be unique, and wedenote it by. Hints: suppose inverses to the same non-zero z ∈ C : a = a ⋅ 1 = a ( z b ) = ( a z )
