Đáp án `+` Giải thích các bước giải:

Bài 25:

`\text{a) 58 . 75 + 58 . 50 - 58 . 25}`

`\text{= 58(75 + 50 - 25)}`

`\text{= 58 . 100}`

`\text{= 5800}`

---

`\text{b) 27 . 39 + 27 . 63 - 2 . 27}`

`\text{= 27(39 + 63 - 27)}`

`\text{= 27 . 100}`

`\text{= 2700}`

---

`\text{c) 128 . 46 + 128 . 32 + 128 . 22}`

`\text{= 128(46 + 32 + 22)}`

`\text{= 128 . 100}`

`\text{= 12800}`

---

`\text{d) 66 . 25 + 28 . 66 + 66 . 14 + 33 . 66}`

`\text{= 66(25 + 28 + 14 + 33)}`

`\text{= 66 . 100}`

`\text{= 6600}`

---

`\text{e) 12 . 35 + 35 . 182 - 35 . 94}`

`\text{= 35(12 + 182 - 94)}`

`\text{= 35 . 100}`

`\text{= 3500}`

---

`\text{f) 47 . 29 - 13 . 29 - 24 . 29}`

`\text{= 29(47 - 13 - 24)}`

`\text{= 29 . 10}`

`\text{= 290}`
