Hi, here in this question we are given that we need to find the power set of p equals to 5 .6 .7.
00:13
Now here we know that power set has 2 to the power n number of elements.
00:17
So here n equals to 3.
00:19
So 2 to the power 3 which means it has 8 element.
00:23
So here the power set of p can be written as equals to 5 null set.
00:38
Then 5, then 6, 7 again will pair two elements 5 .6 again 6 .7 again 5 .7 and further another element would be the last set itself 5 .6 .7.

Now here we need to move towards the second part of the question.
01:10
Here in the second part of the question we are given that there is a set.
01:15
Let the set be a.
01:16
So number of elements is 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10...
