Write down all the subsets of { x,y,zt} and find the power set of S = {4,8,12}.

 Write down all the subsets of { x,y,zt} and find the power set of S = {4,8,12}.

Solution:

The possible subsets of {x,y,z,t} are

{ },{x},{y},{z},{t},{x,y},{x,z},{x,t},{y,z},{y,t},{z,t},{x,y,z},{x,y,t},{x,z,t},{y,z,t}{y,z,t}{x,y,z,t}

the power set of S = {4,8,12} are

P(s) = {{ },{4},{8},{12},{4,8},{4,12},{8,12},{4,8,12}}
