Write the following sets in tabular form :
{x|x is a vowel in the word 'NOTATION'}

Answer

To write the set of vowels in the word 'NOTATION' in tabular form, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the word**: The word given is 'NOTATION'.

2. **List the vowels**: The vowels in the English language are A, E, I, O, and U. We need to check which of these vowels are present in the word 'NOTATION'.

3. **Check each vowel**:
- A: Not present in 'NOTATION'
- E: Not present in 'NOTATION'
- I: Present in 'NOTATION'
- O: Present in 'NOTATION'
- U: Not present in 'NOTATION'

4. **Record the vowels found**: From our checks, we find that the vowels present in 'NOTATION' are I and O. However, O appears twice in the word.

5. **Eliminate duplicates**: Since sets do not contain duplicate elements, we will only include O once.

6. **Write the set in tabular form**: The final set of vowels in 'NOTATION' is {O, I}.

### Final Answer:
The required set in tabular form is:
{O, I}
