Для сравнения выражений необходимо вычислить значения выражений в каждой строке и сравнить их.
(7 + 3)2 и 72 + 32
(7 + 3)2 = 102 = 100
72 + 32 = 49 + 9 = 58
100 > 58
5 ⋅ 42 и (5 ⋅ 4)2
5 ⋅ 42 = 5 ⋅ 16 = 80
(5 ⋅ 4)2 = 202 = 400
80 < 400
(2 ⋅ 7)2 и 22 ⋅ 72
(2 ⋅ 7)2 = 142 = 196
22 ⋅ 72 = 4 ⋅ 49 = 196
196 = 196
(20 / 2)2 и 20 / 22
(20 / 2)2 = 102 = 100
20 / 22 = 20 / 4 = 5
100 > 5
250 / 52 и 250 / 5 ⋅ 5
250 / 52 = 250 / 25 = 10
250 / 5 ⋅ 5 = 50 ⋅ 5 = 250
10 < 250
