Find the product by suitable rearrangement. 8 × 165 × 125

Given: 8 × 165 × 125 The Commutative Property of whole numbers in multiplication refers to moving the numbers without affecting the result of multiplication. Let a , b be two whole numbers, then according to the Commutative Property of whole numbers in multiplication, we get, a × b = b × a Applying the above, we can simplify the sum given to us: 8 × 165 × 125 = 8 × 125 × 165 = 1000 × 165 = 165000 Hence, the required product is 165000 .

Find the product by suitable rearrangement. 6092 × 25 × 40 × 2

Given: 6092 × 25 × 40 × 2 The Associative Property of whole numbers in multiplication refers to grouping the numbers without affecting the result of multiplication. Let a , b be two whole numbers, then according to the Associative Property of whole numbers in multiplication, we get, a × b × c = a × b × c Applying the above, we can simplify the sum given to us: 6092 × 25 × 40 × 2 = 6092 × 25 × 40 × 2 = 6092 × 1000 × 2 = 6092 × 1000 × 2 = 6092 × 2000 = 12184000 Hence, the required product is 12184000 .

Find the product by suitable rearrangement. 725 × 8 × 50 × 20

Given: 725 × 8 × 50 × 20 The Associative Property of whole numbers in multiplication refers to grouping the numbers without affecting the result of multiplication. Let a , b be two whole numbers, then according to the Associative Property of whole numbers in multiplication, we get, a × b × c = a × b × c Applying the above, we can simplify the sum given to us: 725 × 8 × 50 × 20 = 725 × 8 × 50 × 20 = 725 × 8 × 1000 = 725 × 8 × 1000 = 5800 × 1000 = 5800000 Hence, the required product is 5800000 .

Find the product using suitable property. 99 × 581

The given product is 99 × 581 To multiply the given integer we use the Distributive property. = ( 100 - 1 ) × 581 = 58100 - 581 = 57519 Hence, the product is 57519
