Answer:A perfect square is a whole number that results from squaring another whole number. In other words, it's the product of an integer multiplied by itself. Here are 10 examples of perfect squares suitable for an 8th-grade test: Examples: 1. 1: 1 x 1 = 1²2. 4: 2 x 2 = 2²3. 9: 3 x 3 = 3²4. 16: 4 x 4 = 4²5. 25: 5 x 5 = 5²6. 36: 6 x 6 = 6²7. 49: 7 x 7 = 7²8. 64: 8 x 8 = 8²9. 81: 9 x 9 = 9²10. 100: 10 x 10 = 10²Step-by-step explanation:1. 1 (1²): - When we multiply 1 by itself, we get 1. Hence, 1 is a perfect square as it is the square of 1. 2. 4 (2²): - By multiplying 2 by itself, we obtain 4. Therefore, 4 is a perfect square as it is the square of 2. 3. 9 (3²): - Multiplying 3 by itself gives us 9. Hence, 9 is a perfect square since it is the square of 3. 4. 16 (4²): - When 4 is squared (multiplied by itself), it equals 16. Therefore, 16 is a perfect square as it is the square of 4. 5. 25 (5²): - Squaring 5 results in 25. Thus, 25 is a perfect square because it is the square of 5. 6. 36 (6²): - By squaring 6, we get 36. Hence, 36 is a perfect square as it is the square of 6. 7. 49 (7²): - When we square 7 (multiply 7 by itself), we get 49. Therefore, 49 is a perfect square as it is the square of 7. 8. 64 (8²): - Squaring 8 yields 64. Therefore, 64 is a perfect square as it is the square of 8. 9. 81 (9²): - By multiplying 9 by itself, we obtain 81. Hence, 81 is a perfect square since it is the square of 9. 10. 100 (10²): - When 10 is squared, we get 100. Thus, 100 is a perfect square because it is the square of 10.
