Question

Solve the following using properties

1) 125×76×8
2) 128×85+128×15
2)102×105​

Answer 1

Answer:

1.We will use associative and commutative property

125×76×8

=125×8×76(using commutative property )

=(125×8) ×76

=1000×76

=76000

2 .128×85+128×15

We will use distributive property

=128×(85+15)(taking 128 as common using distributive property )

=128×100

=12800

3.102×105

We will use distributive property

=(102×100)+(102×5)[using distributive property ]

=10200+510

=10710
