Answer:

Associative property

Step-by-step explanation:

Associative property allows you to put parenthesis in a part of the equation. We can only apply associative property on a part with multiplication or addition. If you do it with at an equation with subtraction or division you can change the result and make calculation mistake.

In this question, all of the operation used is multiplication. The result won't change even if you put parenthesis, both will give result of 480
