Solution 1

First, let's understand the operations involved in the question.

  1. RoS (R composition S) is a relation from S to R such that for any elements x, y, z, if (x, y) is in S and (y, z) is in R, then (x, z) is in RoS.

  2. (SoR)^-1 is the inverse of the relation SoR. If (x, y) is in SoR, then (y, x) is Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
