To Find: The product

Answer to Problem 79SR
Explanation of Solution
Given information:
Concept and Formula Used:
The product of integers with different sign is negative and with same sign is positive.
Calculation:
The given product is
Using Associative and commutative property of multiplication
As the sign of 2 and 10 is same therefore the sign of the product is positive
The sign of 8 and 9 is same therefore the sign of the product is positive
As the sign of 20 and 72 is same therefore the sign of the product is positive
