To write: the letter of the correct answer corresponding to the property illustrated by the given statement
Answer to Problem 12CR
The correct choice is d
Explanation of Solution
Given information:The statement
The two sides of the given expression show the multiplication of terms in two different ways and that the final expression remains same. Here, the first element of term, a is same in both sides and b and c are multiplied in different order. But irrespective of the order, the result is given to be same. This can be analyzed as below.
Considering the left hand side of the expression and solving it gives,
Now, considering the right hand side, the expression becomes,
Hence, it shows that the order of multiplication of two terms does not change the final result. Thus it illustrates the commutative property for multiplication of numbers.
The correct choice representing this property is d.
