State True or False on a dot pattern of numbers:
Number 8 can be expressed as a square.

Answer

To determine whether the number 8 can be expressed as a square, we will follow the steps outlined in the video transcript.

### Step-by-Step Solution:

1. **Identify the Number**: We need to check if the number 8 can be expressed as a square.

2. **Subtract Odd Numbers**: We will start subtracting the first few odd numbers from 8 until we either reach 0 or go below 0.

- First odd number: 1
- Calculation: \( 8 - 1 = 7 \)

- Second odd number: 3
- Calculation: \( 7 - 3 = 4 \)

- Third odd number: 5
- Calculation: \( 4 - 5 = -1 \)

3. **Evaluate the Result**: After subtracting the odd numbers, we reached -1, which is less than 0. This means we did not reach 0.

4. **Conclusion**: Since we did not reach 0 after subtracting the odd numbers, we conclude that the number 8 cannot be expressed as a square.

5. **Final Answer**: Therefore, the statement "Number 8 can be expressed as a square" is **False**.
