Which property is illustrated by the statement?
(2+3.4) + 6 = 2 + (3.4+6)
associative property of addition
commutative property of multiplication
inverse property of multiplication
commutative property of addition

The given expression represents the Associative Property of Addition.

Step-by-step explanation:

Here, the given expression is given as:

(2+3.4) + 6 = 2 + (3.4+6)

Now, for any 3 terms a, b and c the given properties in the options are described as:

1. Associative Property of Addition

(a +b) + c = a + (b + c)

2. Commutative Property of Multiplication

a x b = b x a

3. Inverse Property of Multiplication

4. Commutative Property of Addition

a+ b = b + a

Hence, from the given expression,we can see that:

(2+3.4) + 6 = 2 + (3.4+6)

⇒(a +b) + c = a + (b + c)

Hence, the expression represents the Associative Property of Addition
