Q4-12 pоints Let ​C ​= {1, 2, 4}, ​A​ = ​C ​×​ C​, аnd define а relаtiоn оn ​A​ by: (​u​, ​v​) ​R ​(​x​, ​y​) if and only if ​uy ​=​ xv​. Prove  that ​R​ is an equivalence relation on ​A​. Remember that the elements of ​A are ordered pairs. ​ Compute the partition ​A/R​ that corresponds to the equivalence relation. Hint: Keep in mind that you are partitioning the 9 elements of ​A ​into blocks. ​
