The perfect squares are 9, 64, and 81.
Solución
To determine which numbers are perfect squares, we need to identify numbers that are the square of an integer.
- **9** = \(3^2\) → Perfect square
- **64** = \(8^2\) → Perfect square
- **32** → Not a perfect square
- **81** = \(9^2\) → Perfect square
- **18** → Not a perfect square
- **20** → Not a perfect square
**Perfect squares from the list:**
1. **9**
2. **64**
3. **81**

Perfect squares are numbers that can be expressed as the product of an integer with itself. For example, 9 is a perfect square because it’s 3×3, and 64 is a perfect square as it's 8×8. Similarly, 81 is also a perfect square since it's 9×9. So, the perfect squares from your list are 9, 64, and 81! If you’re ever stumped on identifying perfect squares, try remembering some common squares: 1 (1x1), 4 (2x2), 9 (3x3), 16 (4x4), and 25 (5x5), and so on. You can even create a fun game by memorizing them or using flashcards to sharpen your skills!
