**Under Route 2-2: Whole Square**

To solve the problem related to whole square under Route 2-2, we need to understand the concept of whole square and how to calculate it. Here's a detailed explanation of the process:

1. **What is a Whole Square?**
- In mathematics, a whole square refers to the square of a whole number.
- A whole number is any positive integer (1, 2, 3, ...) or zero (0).
- The square of a whole number is obtained by multiplying the number by itself.

2. **Finding the Whole Square of a Number**
- To find the whole square of a number, follow these steps:
1. Take a whole number, let's say 'n'.
2. Multiply the number 'n' by itself.
3. The product obtained is the whole square of 'n'.

3. **Example**
- Let's take an example to understand the concept better.
- Consider the whole number '4'.
- To find the whole square of 4, multiply it by itself: 4 * 4 = 16.
- Therefore, the whole square of 4 is 16.

4. **General Formula for Whole Square**
- The general formula to calculate the whole square of a number 'n' is: n^2.
- Here, '^' denotes exponentiation, indicating the power to which the number is raised.

5. **Solving the Problem**
- Now, to solve the problem under Route 2-2 related to whole square, follow these steps:
1. Identify the given number or expression for which you need to find the whole square.
2. Apply the general formula mentioned earlier: square the number or expression.
3. Simplify the expression or calculate the product to obtain the whole square.

By following these steps, you can solve the problem related to whole squares effectively. Remember to understand the concept of whole square and apply the formula correctly. Practice with different examples to strengthen your understanding.
