Answer 1

Answer:

Identity property of multiplication

Step-by-step explanation:

Answer 2

Answer:

Option B) Commutative property of multiplication

Step-by-step explanation:

We are given the following information in the question:

$(3a)\times (9c) = 27ac$

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

The multiplication is shown below:

$(3a)\times (9c) = 27ac\\=(3\times a)\times (9\times c)\\= 3\times (a\times 9)\times c\\= 3\times (9\times a)\times c\\=(3\times 9)\times a\times c\\=27ac$

We used the commutative property of multiplication.

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