Answer 1

4 x 2 x 25 x 10 x 50 x 10 x 100

= ( 4 x 25 ) x ( 2 x 50 ) x 10 x 10 x 100

= 100 x 100 x 10 x 10 x 100

= 100 x 100 x 100 x 100

= 100000000 

Answer 2

4x2x25x10x50x10x100 = (4x25)x(50x2)x(10x10x100)

                                  = 100x100x10000 

                                  = 100000000

Answer 3

4 x 2 x 25 x 10 x 50 x 10 x 100

= ( 4 x 25 ) x ( 2 x 50 ) x ( 10 x 10 x 100 )

= ( 4 x 25 ) x ( 2 x 50 ) x ( 100 x 100 )

= 100 x 100 x 100 x 100

= 100000000

Answer 4

4 x 2 x 25 x 10 x 50 x 10 x 100 =

( 4 x 25 ) x ( 2 x 50 ) x ( 10 x 10 ) x 100 

100 x 100 x 100 x 100 = 100 000 000

Answer 5

4 x 2 x 25 x 10 x 50 x 10 x 100 = (4 x 25 ) x (2 x 50) x (10 x 10) x 100

                                                                 = 100 x 100 x 100 x 100

                                                                 = 10000 x 10000
