Concept explainers
To rewrite: the given expression by Properties of real numbers.
Answer to Problem 23E
Using Associative Property and distributive propertyof real numbers the expression can be written as
Explanation of Solution
Given information:
An expression is given as
Concept used:
Associative Property of multiplication of real numbers:
If three real numbers are multiplied then the result does not depend on the order of multiplication.
Suppose a, b, and c are three real numbers, Associative Property of multiplication says that
Distributive property over addition of real numbers:
Suppose a , b, and c are three real numbers, Distributive property says that
Product of a number with a sum can be changed to sum of products.
Calculation:
Consider the expression and simplify as shown:
Therefore,
