WebOn Z+, define * by a * b = c where c is the smallest integer greater than both a and b. Does it give a binary operation? Please refer to this answer, and ignore the part where I talk about [math]x [/math] and [math]y [/math]: Also, there’s a surprisingly large number of related homework problems here on Quora: Continue Reading 9 1 4 WebAnswer (1 of 5): Yes it certainly does, because for any pair of positive integers a and b you have a well-defined rule that determines a third such integer. That is enough to make it a …

Determining if the binary operation gives a group structure

WebLet * be defined on 2 Z = { 2 n ∣ n ∈ Z } by letting a ∗ b = a + b. I've managed to determine that the operation is closed under ∗ and is associative. It's determining if the operation has an identity element and an inverse element that's the problem. Here's my solution for the identity element: Web$a*b=a+b-ab=1 \implies a(1-b)=1-b \implies a=1 \hspace{0.1cm} or \hspace{0.1cm}b=1$ which is not possible, as both $a$ and $b$ are taken from $\mathbb{R} \backslash \left\{ … dwr art

WebAnswer. The element in the brackets, [ ] is called the representative of the equivalence class. An equivalence class can be represented by any element in that equivalence class. So, in Example 6.3.2 , [S2] = [S3] = [S1] = {S1, S2, S3}. This equality of equivalence classes will be formalized in Lemma 6.3.1. dwraven minecraft build
