2) 3³-2²×6 =
3) (5³ - 10² )×4=​

Answer 1

Ответ:

======================================

1) 3^2 * 2^3 - 4^3 = 9 * 8 - 64 = 72 - 64 = 8

2) 3^3 - 2^2 * 6 = 27 - 4 * 6 = 27 - 23 = 3

3) (5^3 - 10^2) * 4 = (125 - 100) * 4 = 25 * 4 = 100

======================================

Answer 2

1) 3² * 2³ - 4³ = 3² * 2³ - 2³ * 2³ = 2³ * (3² - 2³) = 2³ * (9 - 8) = 2³ * 1 = 8 * 1 = 8;

2) 3³ - 2² * 6 = 3 * 3 * 3 - 2 * 2 * 6 = 27 - 24 = 3;

3) (5³ - 10²) * 4 =​ 4 * (5 * 5 * 5 - 10 * 10) = 4 * (125 - 100) = 4 * 125 - 4 * 100 = 500 - 400 = 100.
