123+123=246

24+24=48

k đi 

k lại

123+123=246

24+24=48

Ai muốn k thì gửi tin nhắn cho tôi !!!

123 + 123 = 246

24 + 24 = 48

\(\frac{123.123}{24.123}=\frac{123}{24}=\frac{41}{8}=5,125\)

\(\frac{123\cdot123}{24\cdot123}\\ =\frac{123}{24}\\ =\frac{41}{8}\)

asuka kurashina làm đúng rồi . chúng mình kết bạn với nhau nhé

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

123.75+123.24+123

=123.(75+24+1)

=123.100

=12300

123*154-24*123-123*30.

=123.(154-24-30)

=123.100=12300

k mk nhé ,thank you nhìu

\(123.154-24.123-123.30\)

\(=123.\left(154-24-30\right)\)

\(=123.100\)

\(=12300\)

Hà Anh Hermione nhớ k 

123*(154-24-30)=123*100=12300

không tin tính lai mà xem

a) \(3119\cdot121-3119\cdot11\cdot11\\ =3119\left(121-11\cdot11\right)\\ =3119\left(121-121\right)\\ =3119\cdot0=0\)

b) \(24\cdot\left(123+87\right)+\left(87+123\right)\cdot76\\ =\left(123+87\right)\left(24+76\right)\\ =210\cdot100=21000\)

=24.210+210.76

=(24+76).210

=100.210

=21000

ok e nha

a) \(3119\cdot121-3119\cdot11\cdot11\)

\(=3119\cdot121-3119\cdot\left(11\cdot11\right)\)

\(=3119\cdot121-3119\cdot121\)

\(=3119\left(121-121\right)\)

\(=0\)

b) \(24\cdot\left(123\cdot87\right)+\left(87\cdot123\right)\cdot76\)

\(=\left(123\cdot87\right)\cdot\left(76+24\right)\)

\(=\left(123\cdot87\right)\cdot100\)

\(=1070100\)
