Write the following sets in tabular form and also in descriptive form :
{x:x is a prime number less than 30}

Answer

To solve the question, we need to express the set of prime numbers less than 30 in both tabular and descriptive forms. Let's break it down step by step.

### Step 1: Understand Prime Numbers
A prime number is defined as a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In simpler terms, a prime number has exactly two distinct positive divisors: 1 and itself.

### Step 2: Identify Prime Numbers Less Than 30
We need to list all the prime numbers that are less than 30. The prime numbers less than 30 are:
- 2
- 3
- 5
- 7
- 11
- 13
- 17
- 19
- 23
- 29

### Step 3: Write in Tabular Form
Now, we will write these prime numbers in a table format.

| Prime Numbers |
|---------------|
| 2 |
| 3 |
| 5 |
| 7 |
| 11 |
| 13 |
| 17 |
| 19 |
| 23 |
| 29 |

### Step 4: Write in Descriptive Form
In descriptive form, we can express the set as follows:
"The set of all prime numbers less than 30 is {2, 3, 5, 7, 11, 13, 17, 19, 23, 29}."

### Final Answer
- **Tabular Form:**

| Prime Numbers |
|---------------|
| 2 |
| 3 |
| 5 |
| 7 |
| 11 |
| 13 |
| 17 |
| 19 |
| 23 |
| 29 |

- **Descriptive Form:**
"The set of all prime numbers less than 30 is {2, 3, 5, 7, 11, 13, 17, 19, 23, 29}."
