Write the following sets in tabular form :
{x:x is a multiple of 11 and `0le x lt 80`}

Answer

To write the set {x: x is a multiple of 11 and 0 ≤ x < 80} in tabular form, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Range**: We need to find multiples of 11 that are greater than or equal to 0 and less than 80. The range is from 0 to 80.

2. **Find Multiples of 11**: The multiples of 11 can be found by multiplying 11 by whole numbers (0, 1, 2, 3, ...). We will continue this until the product is less than 80.

- 11 × 0 = 0
- 11 × 1 = 11
- 11 × 2 = 22
- 11 × 3 = 33
- 11 × 4 = 44
- 11 × 5 = 55
- 11 × 6 = 66
- 11 × 7 = 77
- 11 × 8 = 88 (this is greater than 80, so we stop here)

3. **List the Valid Multiples**: The valid multiples of 11 that we found within the range are:
- 0, 11, 22, 33, 44, 55, 66, 77

4. **Write in Tabular Form**: Now, we can write these multiples in a set notation:
- The set in tabular form is: {0, 11, 22, 33, 44, 55, 66, 77}

### Final Answer:
The set in tabular form is: **{0, 11, 22, 33, 44, 55, 66, 77}**
