Question

Simplify by using suitable properties (also state them ):

 71 x 56 + 29 x 56

 135 x 52 + 135 x 48

 16825 x 16825 – 16825 x 6285

 569 x 17 + 569 x 13 + 569 x 70​

Answer 1

Step-by-step explanation:

1. Take 56 common

56(71+29) = 59* 100 = 5900

2. Take 135 common

135(52+48) = 135* 100 = 13500

3. Take 16825 common

16825(16825- 6285) = 16825* 540

4. Take 569 common

569(17+13+70) = 569(100) = 56900

Answer 2

Step-by-step explanation:..

1. Take 56 common

56(71+29) = 59* 100 = 5900

2. Take 135 common
