Question

Write down all the subsets of the following sets 1. {a}
2. {a,b}
3. {1,2,3}
4. fi

Answer 1

Answer:

formula: 2 raise to n

Step-by-step explanation:

set a consists of one element therefore

subset of set a is void set and set a itself

for set a b

set a b consists of two elements therefore

there will be 4 subsets of set ab

for {1,2,3}

therefore 2³= 8

there will be total 8 subsets
