Question

Write down the power sets of the following set:

X = {a, b, c}

Answer 1

these are some subsets: {a}, {b} and {c}
 and these are subsets: {a, b}, {a, c} and {b, c},
 and {a,b,c} is also a subset of {a,b,c} 
 and the empty set {} is also a subset of {a,b,c}
so all the subsets together make the power set
S= { {}, {a}, {b}, {c}, {a, b}, {a, c}, {b, c}, {a, b, c} }

Answer 2

all subsets together form subset.{0},{a},{b},{c},{a,b}{a,c}{b,c}(a,b,c}
