Given the set a = {x, x 2, XY}, B = {1, x, y}, and satisfying a = B, find the value of real number x, Y & nbsp

∵ a = {x, X2, XY}, B = {1, x, y}, and a = B, ∵ x2 = 1, xy = y or x2 = y, xy = 1, when x2 = 1, xy = y, x = ± 1, if x = 1, then x = X2, which is in contradiction with the mutuality of set elements, so it does not meet the requirements of the topic
