Question

Очень срочно надо 5 примеров (7^3)^-2x7^7= 5^3x5^-5x5^4= (1/4)^-3x(1/4)^2= (0,2^-2)-2= (2/3)^-4:(2/3)^-2=

Answer 1

Ответ:

10 40 24 63 32

Объяснение:

Answer 2

Пример 1:

(7^3)^-2 × 7^7 = 7^(-6) × 7^7 = 7^(7 - 6) = 7^1 = 7

Пример 2:

5^3 × 5^(-5) × 5^4 = 5^(3 - 5 + 4) = 5^2 = 25

Пример 3:

(1/4)^(-3) × (1/4)^2 = 4^3 × 4^(-2) = 4^(3 - 2) = 4^1 = 4

Пример 4:

(0.2^(-2))^(-2) = (0.2^(4))^(-1) = 0.2^(-4) = 1/(0.2^4) = 1/0.0016 = 625

Пример 5:

(2/3)^(-4) ÷ (2/3)^(-2) = (2/3)^(2 - (-4)) = (2/3)^6 = 64/729
