Answer 1

Finding product using suitable properties

By using the distributive property of multiplication over addition

(a) 738 x 103

⇒738 x (100 + 3)

⇒ 738 x 100 + 738 x 3

⇒73800 + 2214

⇒76014

(b) 854 x 102

⇒ 854 x (100 + 2)

⇒ 854 x 100 + 854 x 2

⇒ 85400 + 1708

⇒ 87108

(c) 258 x 1008

⇒ 258 x (1000 + 8)

⇒ 258 x 1000 + 258 x 8

⇒ 258000 + 2064

⇒260064

(d) 1005 x 168

⇒ (1000 + 5) x 168

⇒1000 x 168 + 5 x 168

⇒ 168000 + 840

⇒ 168840
