See the step by step solution

Step by Step Solution

Step-1 – Apply the concept of product

When two or more numbers are multiplied together, it gives a number. The numbers that are being multiplied are called the factors. And the result of the multiplication of numbers is called the product of those numbers.

Step-2 – Associative Property of Multiplication of Real Numbers: 

Suppose a, b, and c is three real numbers.

Associative property of Multiplication

Property: (a·b)·c=a·(b·c)

If you are multiplying three real numbers, the product is always the same regardless of their grouping.

Example: (6·4)·3=6·(4·3)=72

Step-3 – Evaluate the expression

To evaluate the expression33xy, substitute the value of x as 5 and the value of y as – 2 and multiply the numbers as shown below,


Thus, the value of the expression is33xy=-330.
