Find the value using suitable property. 625 × 8 × 5973

Given, 625 × 8 × 5973 When we multiply three or more whole numbers, we group them (using brackets) in any convenient manner and multiply, the result in each case remains the same. If a , b a n d c are three whole numbers, then a × b × c = a × b × c The property used is Associative property of multiplication of whole numbers. For example: 3 × 2 × 5 = 3 × 2 × 5 = 30 ⇒ 625 × 8 × 5973 ⇒ 625 × 8 × 5973 = 625 × 8 × 5973 = 5000 × 5973 = 29865000 Hence, required value is 29865000

Find the value using suitable property. 729 × 27 + 729 × 3

Given, 729 × 27 + 729 × 3 We know that, For any three whole numbers a , b a n d c , a × b + c = a × b + a × c The property used is distributive property of multiplication over addition. 729 × 27 + 729 × 3 = 729 × 27 + 3 = 729 × 30 = 21870 Hence, required value is 21870

Find the value using suitable property. 65218 × 124 - 65218 × 24

Given, 65218 × 124 - 65218 × 24 We know that, For any three whole numbers a , b a n d c , a × b - c = a × b - a × c The property used is distributive property of multiplication over subtraction. 65218 × 124 - 65218 × 24 = 65218 × 124 - 24 = 65218 × 100 = 6521800 Hence, required value is 6521800

Find the value using suitable property. 3510 × 82 + 18 × 351 × 10

Given, 3510 × 82 + 18 × 351 × 10 ⇒ 3510 × 82 + 18 × 3510 We know that, For any three whole numbers a , b a n d c , a × b + c = a × b + a × c The property used is distributive property of multiplication over addition. 3510 × 82 + 18 × 3510 = 3510 × 82 + 18 = 3510 × 100 = 351000 Hence, required value is 351000

Find the value using suitable property. 10876 × 185 - 10876 × 85

Given, 10876 × 185 - 10876 × 85 We know that, For any three whole numbers a , b a n d c , a × b - c = a × b - a × c The property used is distributive property of multiplication over subtraction. 10876 × 185 - 10876 × 85 = 10876 × 185 - 85 = 10876 × 100 = 1087600 Hence, required value is 1087600

Find the value using suitable property. 3845 × 782 + 769 × 5 × 218

Given, 3845 × 782 + 769 × 5 × 218 ⇒ 3845 × 782 + 3845 × 218 We know that, For any three whole numbers a , b a n d c , a × b + c = a × b + a × c The property used is distributive property of multiplication over addition. 3845 × 782 + 3845 × 218 = 3845 × 782 + 218 = 3845 × 1000 = 3845000 Hence, required value is 3845000

Find the value using suitable property. 6785 × 548 + 6785 × 222 + 6785 × 230

Given, 6785 × 548 + 6785 × 222 + 6785 × 230 We know that, For any four whole numbers a , b , c a n d d , a × b + c + d = a × b + a × c + a × d The property used is distributive property of multiplication over addition. 6785 × 548 + 6785 × 222 + 6785 × 230 = 6785 × 548 + 222 + 230 = 6785 × 1000 = 6785000 Hence, required value is 6785000

Solve using suitable property: 123 × 11 - 123 × 10 .

Given, 123 × 11 - 123 × 10 We know that, For any three whole numbers a , b a n d c , a × b - c = a × b - a × c The property used is distributive property of multiplication over subtraction. 123 × 11 - 123 × 10 = 123 × 11 - 10 = 123 × 1 = 123 Hence, required value is 123
