51×115-115×41

Answer 1

104 x (14 + 6 )

= 104 x 20

= 2080

67 x 136 + 33 x 136

= ( 67 + 33 ) x 136 

= 100 x 136 

= 13600

51 x 115 - 115 x 41

= ( 51 - 41 ) x 115

= 10 x 115

= 1150 

Answer 2

104 x ( 14+6 ) 

= 104 x 20  

= 104 x 10 x 2

1040 x 2 =2080 k nha mình đang âm

Answer 3

= 104 x 20 = 2080

= 136 x ( 67 + 33 ) = 136 x 100 = 13600

= 115 x ( 51 - 41 ) =115 x 10 =1150

k nhé may p..............................an

Answer 4

1.104x(14+6)

=104x20

=104x10+104x10

=1040x2

=2080

2.67x136+33x136

=136x(67+33)

=136x100

=13600

3.51x115-115x41

=115x(51-41)

=115x10

=1150

Answer 5

104x(14+16)

=104x30

=3120

67x136+33x136

=136x(67+33)

=136x100

=13600

51x115-115x41

=115x(51-41)

=115x10

=1150

Answer 6

104*[14+6]=104*20=2080

67*136+33*136=136*[67+33]=13600

51*115-115*41=115*[51-41]=1150

Answer 7

   104 x ( 14 + 6 )

= 104 x 20

= 2080

   67 x 136 + 33 x 136

= 136 x ( 67 + 33 )

= 136 x 100

= 13600

   51 x 115 - 115 x 41

= 115 x ( 51 - 41 )

= 115 x 10

= 1150
