Question

If $A=$ {$-1,1$}, then find $A\times A\times A$.

Answer 1

Given: $A=$ {$-1,1$}

Cartesian product of two sets
Cartesian product of three non-empty set is given by
$A\times A\times A=${$(a,b,c):a,b,cϵA$}
So, $A\times A\times A$ {$(-1,-1,-1),(-1,-1,1),(-1,1,-1),(-1,1,1),(1,-1,-1),(1,1,-1),(1,1,1),(1,-1,1)$}.
