Let's go through the exercise you uploaded and complete the missing numbers.

The image contains two sets of mathematical expressions where the missing numbers need to be filled in, along with reasons provided.

### Left Column (Square roots):
1. \( \sqrt{9} = 3 \) because \( 3^2 = 9 \).
2. \( \sqrt{25} = 5 \) because \( 5^2 = 25 \).
3. \( \sqrt{0} = 0 \) because \( 0^2 = 0 \).
4. \( \sqrt{1} = 1 \) because \( 1^2 = 1 \).
5. \( \sqrt{100} = 10 \) because \( 10^2 = 100 \).

### Right Column (Missing values for squares):
1. \( 1^2 = 1 \) because \( 1 \times 1 = 1 \).
2. \( 2^2 = 4 \) because \( 2 \times 2 = 4 \).
3. \( 3^2 = 9 \) because \( 3 \times 3 = 9 \).
4. \( 4^2 = 16 \) because \( 4 \times 4 = 16 \).
5. \( 5^2 = 25 \) because \( 5 \times 5 = 25 \).

Would you like further clarification or more detailed explanations on any of these steps?

Here are five related questions to expand your understanding:
1. What is the square root of 144 and why?
2. How do we calculate the square of negative numbers?
3. What is the general formula for finding the square root of a perfect square?
4. How can we estimate square roots of non-perfect squares?
5. Why is the square root of a number always non-negative?

**Tip:** When calculating square roots, always remember that the square of both positive and negative numbers results in the same value, but the principal (positive) root is used in most cases.

In this exercise, students are asked to complete missing numbers related to square roots and perfect squares. This problem focuses on understanding how to calculate square roots and perfect squares, ideal for Grades 5-7.
