Question

power set of {e,f,m,n,o}

Answer 1

$\{\emptyset,\{e\},\{f\},\{m\},\{n\},\{o\},\{e,f\},\{e,m\},\{e,n\},\{e,o\},\{f,m\},\{f,n\},\\ \{f,o\},\{m,n\},\{m,o\},\{n,o\},\{e,f,m\},\{e,f,n\},\{e,f,o\},\{e,m,n\},\\ \{e,m,o\},\{e,n,o\},\{f,m,n\},\{f,m,o\},\{f,n,o\},\{m,n,o\},\{e,f,m,n\},\\ \{e,f,m,o\},\{e,f,n,o\},\{e,m,n,o\},\{f,m,n,o\},\{e,f,m,n,o\}\}$

Answer 2

$n=5\ \ \ \Rightarrow\ \ \ 2^n=2^5=32$

$\emptyset;\\\{e\},\{f\},\{m\},\{n\},\{o\};\\\{e,f\},\{e,m\},\{e,n\},\{e,o\},\{f,m\},\{f,n\},\{f,o\},\{m,n\},\{m,o\},\{n,o\};\\\{e,f,m\},\{e,f,n\},\{e,f,o\},\{e,m,n\},\{e,m,o\},\{e,n,o\},\{f,m,n\},\\\{f,n,o\},\{f,m,o\},\{m,n,o\};\\\{e,f,m,n\},\{e,f,m,o\},\{e,f,n,o\},\{e,m,n,o\},\{f,m,n,o\};\\\{e,f,m,n,o\}$
