WebLet us see some of the methods to the proof modular multiplicative inverse. Method 1: For the given two integers, say ‘a’ and ‘m’, find the modular multiplicative inverse of ‘a’ under modulo ‘m’. The modular multiplicative inverse of an integer ‘x’ such that. ax ≡ 1 ( mod m ) Web1. (5 points) Let R be the additive group of real numbers, and let R+ be the multiplicative group of positive real numbers. Consider the map ˚: R !R+ given by ˚(x) = 2x. (a) Show that ˚is an isomorphism from R to R+. We need to show that ˚is a bijection, and a homomorphism. ˚injective. Suppose 2x = 2y.
