Answer:
297x(15+5)
297x20
6940
1. 837 + 271 + 363
=837+363+271 (Commutative property)
= 1100 + 271
= 1371 (Closure property)
2. 2*1765*50
=2*50*1765 (Commutative property)
= 100*1765
= 176500 (Closure property)
3. 456*103
= 103*456 (Commutative property)
=103*(400+50+6) (Distributive property)
= (103*400) + (103*50) + (103*6)
= 41200 + 5150 + 618
= 46968 (Closure property)
4. 854*105
= 105*854 (Commutative property)
=105*(800+50+4) (Distributive property)
= (105*800) + (105*50) + (105*4)
= 84000 + 5250 + 420
= 89670 (Closure property)
5. 297*15 + 297*5
= 297(15+5) (Distributive property)
= 297*20
= 5940 (Closure Property)
This is the answer.
Hope you have a great day! :)
