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
