Write the following sets in tabular form and also in descriptive form :
{x:x is a square of a natural number}

Answer

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

### Step 1: Identify Natural Numbers
Natural numbers are the positive integers starting from 1. The first few natural numbers are:
1, 2, 3, 4, 5, ...

### Step 2: Calculate the Squares of Natural Numbers
Next, we need to find the squares of these natural numbers:
- The square of 1 is \(1^2 = 1\)
- The square of 2 is \(2^2 = 4\)
- The square of 3 is \(3^2 = 9\)
- The square of 4 is \(4^2 = 16\)
- The square of 5 is \(5^2 = 25\)

Continuing this process, we can see that the squares will keep increasing as we take higher natural numbers.

### Step 3: Write the Set in Tabular Form
Now, we can write the set of squares in tabular form. We will denote this set as \(A\):
\[ A = \{1, 4, 9, 16, 25, \ldots\} \]

### Step 4: Write the Set in Descriptive Form
In descriptive form, we can express the set as:
- \(A\) is the set of squares of natural numbers.

### Final Answer
Thus, the final answer is:
- **Tabular Form:** \(A = \{1, 4, 9, 16, 25, \ldots\}\)
- **Descriptive Form:** \(A\) is the set of squares of natural numbers.
