Решение:
Используем свойства степеней:
- 1) 81 ⋅ 32
81 = 34
34 ⋅ 32 = 34+2 = 36
36 = (33)2 = 272 = 729 - 2) 43 ⋅ 82
4 = 22, 8 = 23
(22)3 ⋅ (23)2 = 22⋅3 ⋅ 23⋅2 = 26 ⋅ 26 = 26+6 = 212
212 = (26)2 = 642 = 4096 - 3) 1002 ⋅ 10003
100 = 102, 1000 = 103
(102)2 ⋅ (103)3 = 102⋅2 ⋅ 103⋅3 = 104 ⋅ 109 = 104+9 = 1013
Ответ: 1) 36 = 729; 2) 212 = 4096; 3) 1013.
