Question

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

Answer 1

$\begin{array}{c}A\times A\times A\times =\left\{1,2\right\}\times \left\{1,2\right\}\times \left\{1,2\right\}\\ =\{\left(1,1,1\right),\left(1,1,2\right),\left(1,2,1\right)\\ \left(1,2,2\right),\left(2,1,1\right),\left(2,1,2\right)\\ \left(2,2,1\right),\left(\mathrm{2.2.2}\right)\}\end{array}$
