Question

IF A=[a b], then the power sel or Als
​

Answer 1

Answer:

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

Step-by-step explanation:

Things to remember:

• The set of all sub sets of a set A is called the power set of A .
• It is denoted by P(A)
• If the number of elements of a set Is 'n' then the total number of all subsets of the set is 2^n.

Given :The set A={a,b}

The number of elements in A is 2

according to the formula ,

total number of subsets of the set A is 2^2=4

they are pi,{a},{b},a,b}

The power set of A is P(A)= {pi,{a},{b},{a,b}}
