00:00So what are equal sets? What are they called?
00:02Now let's look at this, folks.
00:04Consisting of the same elements.
00:14Two sets that are friends are called equal sets.
00:28Let's give an example right away, folks.
00:36What should our set A be?
00:41Let it consist of one, two, five, or ten elements.
00:46Let's say our set B is x. So, what does x consist of?
00:54What is the number ten?
00:58Let it consist of its positive integer divisors.
01:06I'll go over there.
01:12They are exact divisors, folks.
01:14Let's say our problem is that we need to show that these two sets are equal.
01:32Now, let's move on to our solution.
01:40Friends, the number ten, now set A is clearly defined.
01:44It consists of one, two, five, ten, right guys?
01:46Set B consists of the positive integer divisors of the number ten.
01:49So, what are the positive integer divisors of ten when we divide the number?
02:10When you factorize the prime factors.
02:11Isn't it one, two, five, ten, ten?
02:16Yes.
02:19So, friends.
02:23What does equals in B?
02:26So, it consists of the elements one, two, five, and ten.
02:32So, what do we call sets A and B, my friends?
02:44It is said to be equal to.
02:46Right, guys?
02:47And how is it shown, friends?
02:50It is shown as A equals B.
