Answers
Step-by-step explanation:
Which property are u about asking
Answer:
i.e.,a × (b + c) = a × b + a × c
(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) 258 × 1008 = 258 × (1000 + 8)
= 258 × 1000 + 258 × 8
= 258000 + 2064
= 260064
(d) 1005 × 168 = 168 × 1005
= 168 × (1000 + 5)
= 168 × 1000 + 168 × 5
= 168000 + 840
= 168840
Thus, the answers are (a) 76014 (b) 87108 (c) 260064 (d) 168840
