Answer 2

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.

Therefore, Option A is correct.
