Question

In Exercises 19-22, rewrite the expression using the given property of real numbers.

Associative property of multiplication$7\left(3x\right)$

Short answer

Using the associative property of multiplication, expression can be rewritten as $7\left(3x\right)=\left(7\cdot 3\right)x$.

Step-by-step solution

Step 1. Definition of the Associative property of addition.

The associative property is the property in which when the three numbers are multiplied, it doesn’t matter which two numbers are multiplied first.

Step 2. Finding the property used.

In the Associative property of multiplication, the order of the numbers which are multiplying first doesn’t affect the answer.

Step 3. using a property.

Since the order of the number does not affect the answer.

Therefore expression can be rewritten as,$7\left(3x\right)=\left(7\cdot 3\right)x$
