2. $=234\times (1257-257)=234\times 1000=234000$

3. $=175\times (1274-273-1)=175\times 1000=175000$

4. $=(4\times 25)\times (125\times 8)=100\times 1000=100000$

a) 425 x 3475 + 425 x 6525
= 425 x (3475 + 6525)
= 425 x 10000
= 4250000
b) 175 x 1274 - 175 x 273 - 175
= 175 x 1274 - 175 x 273 - 175 x 1
= 175 x (1274 - 273 - 1)

173726 nhé bạn ê

a) `123 - 27 + 27 + 13 - 123`

`= (123 - 123) + (27 - 27) + 13`

`= 0 + 0 + 13`

`= 13`

`---`

b) `175 + 25 + 13 + 15 - 175 - 25`

`= (175-175)+(25-25)+25+13`

`=0+0+25+13`

`=28`
