2010 + 2010 + 2010 + 2010 - 2010 x 4

= (2010 x 4) - (2010 x 4)

= 8040 - 8040

=  0

(tick giúp mình nha)

2010+2010+2010+2010-2010x4

=2010x1+2010x1+2010x1+2010x1-2010x4

=2010x(1+1+1+1-4)

=2010x0

=0

= ( 1 + 3 + 5 + ... + 2011 ) - ( 2 + 6 + 8 + ... + 2010 )

= [ 1006 x ( 2011 + 1 ) : 2 ] - [ 1005 x ( 2010 + 2 ) : 2 ]

= ( 1006 x 2012 : 2 ) - ( 1005 x 2012 : 2 )

= ( 2024072 : 2 ) - ( 2022060 : 2 )

= 1012036 - 1011030

= 1006

m giong ban kia !ban nao tk mk di !

1 + 2 - 3 - 4 + 5 + 6 - 7 - 8 + 9 + ... + 2006 - 2007 - 2008 + 2009 - 2010 - 2011 = 1006

`1/2:3/4+5/6:3/4-2/8:3/4`

`=1/2 xx 4/3 + 5/6 xx 4/3 - 2/8 xx 4/3`

`=4/3 xx ( 1/2 + 5/6 - 2/8)`

`=4/3 xx ( 1/2 + 5/6 - 1/4 )`

`=4/3 xx ( 6/12 + 10/12 - 3/12)`

`=4/3 xx ( 16/12 - 3/12)`

`=4/3 xx 13/12`

`=13/9`

Ai trả lời giúp đi mòa plz

=2010 x ( 3+6+1)                                                                     

=2010 x 10                                                                                                     

=20100

  2010 x 3 + 2010 x 6 + 2010

=  2010 x ( 3 + 6 + 1 )

=  2010 x 10

= 20100

Lời giải:

$2010\times 4+1005\times 190+2019$

$=1005\times 2\times 4+1005\times 190+2019$

$=1005\times 8+1005\times 190+2019$

$=1005\times (8+190)+2019=1005\times 198+2019=201009$

2010 * 4 - 2010 * 4

=.......... r bạn tự tính 

66-66=..........bạn tự tính

Cau 1:

Ban lay 4 so 2010 = 2010 x 4. Nhu vay 4 so 2010 - 2010 x 4 la het con so 1 so 2010 .Vay dap so:2010

Cau 2:

Co 11 so 6 ban lay 6 x 11 = 66.Nhu vay 66 - 66 = 0.Dap so:0

=66-(6x11)

=66-66

=0

đề bài hơi sai tí nên cj sửa cho e nha để cho tròn tại số lớn quá với lại xấu 

18,85 × 2010 - 65 × 18,85 -  945 x 18,85

= 18,85 x ( 2010 - 65 - 945) 

= 18,85 x 1000

= 18850

\(18,85\) x \(2010-65\) x \(18,85\) x \(945\)

\(=18,85\) x \(\left(2010-65\right)\) x \(945\)

\(=18,85\) x \(1945\) x \(945\)

\(=18,85\) x \(1838025\)

\(=34646771,25\)
