Solution
The correct option is D 5600
5 × 7 × 2 × 2 × 8 × 5
= 5 × (2 × 7) × 2 × (5 × 8)
[using commutative property]
= (5 × 2) × 7 × (2 × 5) × 8
[using associative property]
= 10 × 7 × 10 × 8
= 70 × 80
= 5600
5 × 7 × 2 × 2 × 8 × 5
= 5 × (2 × 7) × 2 × (5 × 8)
[using commutative property]
= (5 × 2) × 7 × (2 × 5) × 8
[using associative property]
= 10 × 7 × 10 × 8
= 70 × 80
= 5600
