Determine the number of subsets and list down all of them. 1. { a, b,c }
2.{ 2,4,6,8 }
3.{ 1,2,3,4,5,}
4.{d, e,f, g,h, i}​

We have to use Powerset .All of the elements are subsets of the set.

If n(A)=n

#1

{a,b,c}It has 2^3=8subsets

Now

P(A)={{a},{b},{c},{a,b},{a,c},{b,c},{a,b,c}}

#2

{2,4,6,8}It has 2^4=16 subsets

Now

P(A)={{2},{4},{6},{8},{2,4},{2,8},{2,8},{4,8},{4,6},{6,8},{2,4,6},{2,4,8},{2,6,8},{4,6,8},{2,4,6,8}}

#3

It has 2^5=32 subsets

Now

P(A)={{1},{2},{3},{4},{5},{1,2},{1,3},{1,4},{1,5},{2,3},{2,4},{2,5},{3,4},{3,5},{4,5},{1,2,3},{1,2,4},{1,2,5}...{1,2,3,4,5}}
