 Hi and welcome to the session. I am Priyanka and this is the question which we need to do. It says if A is equal to minus 1 comma 1, find A cross A cross A. So let us start with our solution. Here we are given set A having elements as minus 1, 1. And now we are required to find A cross A cross A. So first of all we will find out A cross A. That will be, let us write down the elements of set A in our rough column twice. That will make our work a little easier. Now the ordered pair will be formed with the first element of the first set with the first element of the second set. So it will be minus 1, minus 1. Then the first element of the first set with the second element of the second set that will be minus 1, 1. Then the second element of the first with the first element of the second and the last one will be 1 comma 1. Right, so A cross A are having four elements to it. Now we need to find A cross A cross A. That will be the set A cross A with again A. So each element of proceeding on. Now the first element of set A cross A is minus 1, minus 1. It will be paired with the first element of the set A. And now the ordered pair will be minus 1, minus 1, minus 1. Then minus 1, 1. Then again minus 1. That means we are pairing this, the first element of set A with each and every element also. Proceeding on 1, minus 1, minus 1, 1, 1, minus 1. Now the first element will be paired with the second element. And this is how we will make more four elements to set A cross A cross A. And 1, minus 1, 1, 1, 1, 1. Right, so these are the elements. So this completes finding all the elements of A cross A cross A. So for solving the given problem we use the concept of ordered triplet. We defined A cross A cross A as A comma B comma C in which A, B, C belongs to A. Where A is a non-empty set and with its help found out the required result. So this ends the question that was given to us. I hope you enjoyed the session and bye for now.
