Determine wether the two expressions are equivalent. If so,tell what property is applied. If not explain why.
1) 9 x 1 and 9. Is this expression equivalent because 9 x 1=9 and also 1 x 9=9.this would be an example of an communitive property.
2) 7 x 3 and 3 x 7. This expression would be equivalent because no matter which position the. Numbers are swithched around,theyb will alsways get the same answer.this is an example of the associative property.
Can someone please check this for me???
