1. 13²-12² = 169 - 125 = √25 = 5
2. 21.8² - 18.2² = 475.24 - 331.24 = √144 = 12
3. 313² - 312² = 97969 - 97344 = √625 = 25
4. 17² - 64 = 289 - 64 = √225 = 15
5. 45.8² - 44.2² = 2097.64 - 1953.64 = √ 144 = 12
6. 117² - 108² = 13689 - 11664 = √2025 = 45
7. 6.8² - 3.2² = 46.24 - 10.24 = √36 = 6
8. 2 цел. 3/5 ² - 2 цел. 2/5² = 2 цел. 9/25 - 2 цел. 4/25 = √5/25 = 5/5 = 1
