Complex numbers multiplicative inverse
Web8. 1+0i is _____ for complex number z. a) additive inverse b) additive identity element c) multiplicative identity element d) multiplicative inverse View Answer. Answer: c Explanation: On multiplying one (1+0i) to a complex number, we get same complex number so 1+0i is multiplicative identity element for complex number z i.e. z*1=z. 9. … WebProof. Uniqueness. A complex number w is an inverse of z if zw = 1 (by the commutativity of complex multiplication this is equivalent to wz = 1). We will first prove that if w and v are two complex numbers, such that zw = 1 and zv = 1, then we necessarily have w = v. This means that any z ∈ C can have at most one inverse.
