Find the Power Set A=(8,13,15)

The power set of a set ${\displaystyle S}$ is the set of all subsets of ${\displaystyle S}$. The first subset will be set ${\displaystyle S}$ itself. Next, find all subsets that contain one less element (in this case ${\displaystyle 2}$ elements). Continue with this process until finding all subsets including the empty set.

Power Set = ${\displaystyle \{\{8,13,15\},\{13,15\},\{8,13\},\{8,15\},\left\{13\right\},\left\{15\right\},\left\{8\right\},\left\{\right\}\}}$
