Question

if A={-1,1} and B={-1,1} then geometrically describe the set of points of A*B​

Answer 1

Answer:

Step-by-step explanation:

A=(-1,1) and B=(-1,1)

A × B= { (-1,-1),(-1,1),(1,-1),(1,1)}

Answer 2

The required set is {(-1,-1),(-1,1),(1,-1),(1,1)}.

Step-by-step explanation:

The given sets are

A={-1,1} and B={-1,1}

We need to find the set of points of A*B​.

$A\times B=\{(a,b)|a\in A,b\in B\}$

Using this we get

$A\times B=\{(-1,-1),(-1,1),(1,-1),(1,1)\}$

Therefore, the required set is {(-1,-1),(-1,1),(1,-1),(1,1)}.
