Answer 2

Let's calculate the expressions step by step:

1. 189•7 + 189•93: = 189 * 7 + 189 * 93 = 1,323 + 17,577 = 18,900

2. 257•127 - 257•27: = 257 * 127 - 257 * 27 = 32,639 - 6,939 = 25,700

3. 4•153•25: = 4 * 153 * 25 = 612 * 25 = 15,300

So, the answers are:

1. 189•7 + 189•93 = 18,900
2. 257•127 - 257•27 = 25,700
3. 4•153•25 = 15,300
