Answer 2

Answer:

1)in first case take 125 as common and take it out

=125(56 + 44)

=125(100)

=12500

take 125 as common and write remains two numbers inside bracket and put the sign used to compute it

a(b+c)=ab+ac

2)25 is first multiplied by 4 and then it is multiplies with 365

25×4 is 100 and then 100 ×365= 36500

3)take 9 commonly as out side

9(1+11+111+1111)

9×1234

11106
