Question

If A = {-1,1},FIND A*A*A

Answer 1

A*A*A={-1,1}*{-1,1}*{-1,1}
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}

Answer 2

Answer:

It is known that for any non-empty set A, A x A x A is defined as

A x A x A = {(a,b,c): a,b,c ∈ A}

It is given that A = {-1,1}

Therefore

A x A x 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}

Hope it Helps!
