I want the properties involved in each:-
1. 15 + 34 = 34 + 15
2. 738 x 1 = 738
3. 4 x 85 = 85 x 4
4. 94 x 0 = 0
5. (71+26) + 53 = 71 + (26 + 53)
6. (294 x 3) x 5 294 x (3 x 5)
7. 79 x 0 = 0
8. 28 + 53 +72 = 53 + 100
9.5 x 303 x 4 = 303 x 20
80 x 10 = 10 = 80

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
(c) 258 × 1008
= 258 × (1000 + 8)
= 258 × 1000 + 258 × 8
= 258000 + 2064
= 260064
(d) 1005 × 168
= (1000 + 5) × 168
= 1000 × 168 + 5 × 168
= 168000 + 840
