B. Commutative property of multiplication

C. Zero property of multiplication

D. Identity property of multiplication

Answer 1

Identity property of multiplication

Explanation:

Answer 2

Option B) Commutative property of multiplication

Explanation:

We are given the following information in the question:

`(3a)* (9c) = 27ac`

We have to find the property of multiplication used in the above expression:

The multiplication is shown below:

`(3a)* (9c) = 27ac\\=(3* a)* (9* c)\\= 3* (a* 9)* c\\= 3* (9* a)* c\\=(3* 9)* a* c\\=27ac`

We used the commutative property of multiplication.

Commutative property states that two numbers can be multiplied in any order
