Answer 5

*Cách 1: (9.6 -4.2) x3.6= 5.4x3.6=19.44

*Cách 2: (9.6 -4.2) x3.6=(9.6x3.6) - (4.2x3.6)= 34.56 -15.12=19.44

Answer 6

C1 :

( 9,6 - 4,2 ) x 3,6 

= 5,4 x 3,6 

= 19,44

C2:

( 9,6 - 4,2 ) x 3,6

= 9,6 x 3,6 - 4,2 x 3,6

= 34,56 - 15,12 = 19,44

Answer 7

C1:(9.6-4.2)x3.6

=5.4x3.6

=19.44

C2:(9.6-4.2)x3.6
