Step-by-step explanation:

From the above question,

They have given :

1. The distributive property states that when a number is multiplied by a group of numbers, it is the same as multiplying each number in the group by the number.

2. The associative property states that the order in which two or more numbers are added or multiplied does not affect the result.

3. The commutative property states that when two or more numbers are added or multiplied, the order in which they are added or multiplied does not affect the result.

4. The identity property states that any number added to or multiplied by zero will result in the same number.

5. The inverse property states that when a number is added to its opposite, the result will always be zero.

Hence,

         1. 7a(a)

         2. (7b)a

         3. 5 + 8

         4. – 4(0)

         5. 0
