Answer:

Option A - 4(2a\cdot5) = (4\cdot2a) \cdot5

Step-by-step explanation:

Given : Pair of expressions.

A. 4(2a\cdot5) = (4\cdot2a) \cdot5

B. 4(2a\cdot5) = 8a\cdot20

C. 4(2a\cdot5) = (2a\cdot 5) \cdot4

D. 4(2a\cdot5) = 4\cdot 2a\cdot5

To find : Which pair of expressions is equivalent using the Associative Property of Multiplication?

Solution :

Associative Property of Multiplication states that multiplication of group of numbers in any combination.

a\cdot(b\cdot c)=(a\cdot b)\cdot c

On comparison with property,

4(2a\cdot5) = (4\cdot2a) \cdot5 satisfy the condition.

Where, a=4, b=2a and c=5.
