ifA={1,2} and B={4,5} find A×B and B×A. Also find n A×B, n(B×A). prove that A×B= B×A but n (A×B) =n (B×A)=n(A)×n(B).​

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
