Which of the following shows an equivalent expression to [(5*3)*12] if only the associative property was used to transform the expression?

a) [5*(3*12)]

b) [(5*12)*3]

c) [(3*5)*12]

d) [12*(3*5)

By using the associative property [(5*3)*12] is equal to

[5*(3*12)] .

Option (A) is correct .

Step-by-step explanation:

Definition of associative property of multiplication

Let us assume that x , y and z be the three real numbers .

x × (y × z ) = (x × y) × z

This is called the associative property .

As given the expression be as follow

= [(5*3)*12]

Here

x = 5 , y = 3 , z = 12

By using the associative property

[(5*3)*12] = [5*(3*12)]

Therefore by using the associative property [(5*3)*12] is equal to

[5*(3*12)] .

Option (A) is correct .
