123 + 123 + 123=369

23+23+23=69

a, 369

b, 69

k nhé

thanks

369;69

nha ban

chuc ban hoc gioi

123+123=246

23+23=46

123 + 123 = 246

23 + 23 = 46

k miks

= 246

= 46
Chúc bạn học giỏi <3

123+123=123x2=246

23+23=23x2=46

kick mik nha bạn

123+123=246

23+23=46

123+123=246

23+23=46

Kb nhé

\(12+23>23:23\)

\(123-123=22-22\)

\(13-6< 23\)

\(90-3>24\)

12+23>23:23     13-6<23

123-123=22-22     90-3>24

.

Trả lời:

12 + 23 > 23 : 23

123 - 123 = 22 - 22

 13 - 6 < 23 

90 - 3 > 24

1 câu hay 2 câu vậy bn

a: \(-81\cdot36+\left(-81\right)\cdot63-81\)

\(=36\cdot\left(-81\right)+63\cdot\left(-81\right)+\left(-81\right)\)

\(=-81\left(36+63+1\right)\)

\(=-81\cdot100=-8100\)

b: \(23\cdot\left(-38+123\right)-123\cdot\left(23-38\right)\)

\(=-23\cdot38+23\cdot123-123\cdot23+123\cdot38\)

\(=123\cdot38-23\cdot38=38\left(123-23\right)=38\cdot100=3800\)

a, \(=123.\left(1+43+56\right)\)

\(=123.100\)

\(=12300\)

b, \(=23.101\)

\(=2323\)

a, 123 + 123 . 43 + 123 . 56 

=123x(1+43+56)

=123x100

=12300

b, 23 + 23 + 23 + ... + 23 (có 101 số 23)

=101x23

=2323

Mấy bạn ko làm bài cuối à?

`123xx77+123xx23`

`=123xx(77+23)`

`=123xx100`

`=12300`

123+123=246

24+23=47

123+123=246

24+23=47

 k nha 

123+123=246

24+23=47

Kb nha

Nếu muốn k thì gwuir tin nhắn cho mk nha
