Решение:
a) 9² + 19 = 81 + 19 = 100
б) 17² - 209 = 289 - 209 = 80
в) 6³ : 3 = 216 : 3 = 72
г) 2³ ⋅ 3² = 8 ⋅ 9 = 72
д) (15 - 7)² : 2³ = 8² : 8 = 64 : 8 = 8
e) (17 - 16)⁸ + 2⁵ = 1⁸ + 32 = 1 + 32 = 33
ж) 10⁶ - 20⁴ = 1000000 - 160000 = 840000
з) 3⁴ ⋅ 10⁴ = 81 ⋅ 10000 = 810000
и) 5⁴ : 5² = 625 : 25 = 25
