Find the product using suitable properties.

(a) 738 × 103 (b) 854 × 102


(c) 258 × 1008 (d) 1005 × 168


(a) 738×103


By using distributive property;


We get,


= 738(100+3)


= 738×100+738×3


= 73800+2214


= 76014


(b) 854 × 102


By using distributive property, we get,


= 854 × (100+2)


= 854×100+854×2


= 85400+1708


= 87108


(c) 258 × 1008


By using distributive property, we get,


= 258 × (1000+8)


= 258×1000+258×8


= 258000+2064


= 260064


(d) 1005×168


By using distributive property, we get,


= (1000+5) ×168


= 1000×168+5×168


= 168000+840


= 168840
