Давайте найдем значения выражений для указанных чисел:
а) 8 и 2:
1) \(8^2 + 2^2 = 64 + 4 = 68\)
2) \((8 + 2)^2 = 10^2 = 100\)
3) \(8^2 - 2^2 = 64 - 4 = 60\)
4) \((8 - 2)^2 = 6^2 = 36\)
б) -4 и 3:
1) \((-4)^2 + 3^2 = 16 + 9 = 25\)
2) \((-4 + 3)^2 = (-1)^2 = 1\)
3) \((-4)^2 - 3^2 = 16 - 9 = 7\)
4) \((-4 - 3)^2 = (-7)^2 = 49\)
в) 7 и -5:
1) \(7^2 + (-5)^2 = 49 + 25 = 74\)
2) \((7 + (-5))^2 = (2)^2 = 4\)
3) \(7^2 - (-5)^2 = 49 - 25 = 24\)
4) \((7 - (-5))^2 = (12)^2 = 144\)
г) -9 и -6:
1) \((-9)^2 + (-6)^2 = 81 + 36 = 117\)
2) \((-9 + (-6))^2 = (-15)^2 = 225\)
3) \((-9)^2 - (-6)^2 = 81 - 36 = 45\)
4) \((-9 - (-6))^2 = (-3)^2 = 9\)
