(c) 256 x 1008
d)728 x 101
e) 824 x 25​

Answer 1

Answers:

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

c) 256 × 1008

= 256 × (1000 + 8)

= (256 × 1000) + (256 × 8)

= 256000 + 2048

= 258048

d) 728 × 101

= 728 × (100 + 1)

= (728 × 100) + (728 × 1)

= 72800 + 728

= 73528
