Answer»

Answer:

(a) 738 × 103

= 738 × (100 + 3)

= 738 × 100 + 738 × 3

= 73800 + 2214

= 76014

(b) 854 × 102

= 854 × (100 + 2)

= 854 × 100 + 854 × 2

= 85400 + 1708

= 87108

= 258 × (1000 + 8)

= 258 × 1000 + 258 × 8

= 258000 + 2064

= 260064

(d) 1005 × 168

= (1000 + 5) × 168

= 1000 × 168 + 5 × 168

= 168000 + 840

= 168840
