- Identify the following:

1. The largest two-digit number that can be rounded to 10

2. The smallest two-digit number that can be rounded to 100

3. The largest four-digit number that can be rounded to 3 000

4. The smallest five-digit number that can be rounded to 10 000

5. The largest five-digit number that can be rounded to 20 000

Let's solve each problem one by one by rounding the numbers to the nearest place value as specified:

### 1. **The largest two-digit number that can be rounded to 10**
- We are rounding to the nearest 10.
- Numbers from 5 to 14 round to 10.
- Therefore, the largest two-digit number that can be rounded to 10 is **14**.

### 2. **The smallest two-digit number that can be rounded to 100**
- We are rounding to the nearest 100.
- Numbers from 50 to 149 round to 100.
- Therefore, the smallest two-digit number that can be rounded to 100 is **50**.

### 3. **The largest four-digit number that can be rounded to 3,000**
- We are rounding to the nearest 1,000.
- Numbers from 2,500 to 3,499 round to 3,000.
- Therefore, the largest four-digit number that can be rounded to 3,000 is **3,499**.

### 4. **The smallest five-digit number that can be rounded to 10,000**
- We are rounding to the nearest 10,000.
- Numbers from 5,000 to 14,999 round to 10,000.
- Therefore, the smallest five-digit number that can be rounded to 10,000 is **5,000**.

### 5. **The largest five-digit number that can be rounded to 20,000**
- We are rounding to the nearest 10,000.
- Numbers from 15,000 to 24,999 round to 20,000.
- Therefore, the largest five-digit number that can be rounded to 20,000 is **24,999**.

### Summary of answers:
1. **14**
2. **50**
3. **3,499**
4. **5,000**
5. **24,999**
