Question

If A= {1,2} and B={1,3} Find AXB and BXA

Answer 1

Step-by-step explanation:

AXB = {1,2} X {1,3}

={(1,1)(1,3)(2,1)(2,3)}

BXA = {1,3} X {1,2}

={(1,1)(1,2)(3,1)(3,2)}

Answer 2

Answer:

Sets exist as a systematized collection of objects and can be described in set-builder form or roster form.

Step-by-step explanation:

Sets exist as a systematized collection of objects and can be described in set-builder form or roster form. Usually, sets are described in curly braces {}.

Given,

A= {1,2}

B={1,3}

To find,

AXB and BXA

Step 1

$A=\{1,2\}$ and $B=\{1,3\}$

$A \times B=\{1,2\} \times\{1,3\}$

$=\{(1,1),(1,3),(2,1),(2,3)\}$

$B \times A=\{1,3\} \times\{1,2\}$

$=\{(1,1),(1,2),(3,1),(3,2)\}$
