Question

Which property is demonstrated in the equation 7×(8×9) = (7×8)×9

A)Symmetric
B)commutative
C)property of zero
D)associative

Answer 1

For this case we have that by definition, the associative property is defined as:

$(a * b) * c = a * (b * c)$

So, if we have the following expression:

$7 * (8 * 9) = (7 * 8) * 9$

According to the mentioned property we can verify that it is the associative property.

Answer:

Associative property
