Question

choose the property of real numbers that justifies the equation.
$a\cdot 6 = 6\cdot a$
$0 + 4 = 4$
$7 + n = n + 7$
$0\cdot 2 = 0$

Explanation:

1. For $a \cdot 6 = 6 \cdot a$: The order of multiplication does not change the product.
2. For $0 + 4 = 4$: Adding 0 to a number leaves it unchanged.
3. For $7 + n = n + 7$: The order of addition does not change the sum.
4. For $0 \cdot 2 = 0$: Multiplying any number by 0 results in 0.

Answer:

1. $a \cdot 6 = 6 \cdot a$: Commutative Property of Multiplication
2. $0 + 4 = 4$: Identity Property of Addition
3. $7 + n = n + 7$: Commutative Property of Addition
4. $0 \cdot 2 = 0$: Zero Property of Multiplication
