If A = -1, 1 , find A × A × A. - Vidyadip

Question

If A = {-1, 1}, find A × A × A.

✓

Answer

We have,
A = {-1, 1}
$\therefore$ A × A = {-1, 1} × {-1, 1}
= {(-1, -1), (-1, 1), (1, -1), (1, 1)}
$\therefore$ A × A × 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, -1), (1, -1, 1), (1, 1, -1), (1, 1, 1)}
