2) 25600

3) 21800

4) 4280000

Answer 2

Answer:

I) 8×114×125

= 114 × (125×8) [ Associative property]

= 114×1000

= 114000

ii) 4×128×50

= 128 × (4×50) [Associative Property]

= 128 × 200

= 25600

iii) 2×218×50

= 218×(2×50) [Associative Property]

= 218×100

=21800

iv) 16×428×625

=428×(625×16) [Associative Property]

=428×10000

=4280000

Hope it helps :)
