a) 27 x 35 + 73 x 6 - 27 x 29

= 27 x ( 35 - 29 ) + 73 x 6

= 27 x 6 + 73 x 6

= 6 x ( 27 + 73 )

= 6 x 100

= 600

b) 29 x ( 47 + 53 ) - 47 x ( 29 + 53 )

= 29 x 47 + 29 x 53 - 47 x 29 + 47 x 53

= 29 x ( 47 + 53 - 47 ) + 47 x 53

= 29 x 53 + 47 x 53

= 53 x ( 29 + 47 )

= 53 x 76

= 4028

c) 5 x 17 x 4 x 25 x 20

= ( 5 x 20 ) x ( 4 x 25 ) x 17

= 100 x 100 x 17

= 10000 x 17

= 170000
