Answer:
by using the associative property [(5*3)*12] = [5*(3*12)] .
Step-by-step explanation:
Given : [(5x3)x12]
To find : which of the following shows an equivalent expression to [(5x3)x12] if only the associative property is used to transform the expression.
Solution : We have given that [(5x3)x12]
Let 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] = [5*(3*12)] .
