Question

If $P=$ {$1,2$}, form the set $P\times P\times P$.

Answer 1

Given: $P=\{1,2\}$
$(P\times P\times P)=\{1,2\}\times \{1,2\}\times \{1,2\}$
$=\left\{\right(1,1),(1,2),(2,1),(2,2\left)\right\}\times \{1,2\}$
$=\left\{\right(1,1,1),(1,1,2),(1,2,1),(1,2,2),(2,1,1),(2,1,2),(2,2,1),(2,2,2\left)\right\}$
