Answer 1

1) (1,3m^2 + 4n^2)^2 = (1.3m^2)^2 + 2 * 1.3m^2 * 4n^2 + (4n^2)^2 = 1.69m^4 + 16.8m^2n^2 + 16n^4

2) (2.5a^2 + 4b)^2 = (2.5a^2)^2 + 2 * 2.5a^2 * 4b + (4b)^2 = 6.25a^4 + 20a^2b + 16b^2

3) (5/2p - 0.5q^3)^2 = (5/2p)^2 - 2 * (5/2p) * 0.5q^3 + (0.5q^3)^2 = 25/4p^2 + 2.5pq^3 + 0.25q^6

4) (2.4m^3 - 3/4t)^2 = (2.4m^3)^2 - 2 * 2.4m^3 * 3/4t + (3/4t)^2 = 5.76m^6 + 3.6m^3t + 9/16t^2

5) (7/4 + 0.6b^4)^3 = (7/4)^3 + 3 * (7/4)^2 * 0.6b^4 + 3 * (7/4) * (0.6b^4)^2 + (0.6b^4)^3 = 343/512 + 2.52b^4 + 3.24b^8 + 0.216b^12

6) (3/8a - 2/3b^4)^2 = (3/8a)^2 - 2 * (3/8a) * (2/3b^4) + (2/3b^4)^2 = 9/64a^2 - 4/24ab^4 + 4/9b^8

Answer 2

Спасибо за вопрос! Я помогу вам раскрыть каждое выражение. Вот их пошаговое решение:

1. (1,3m^2 + 4n^2)^2 = (1.3m^2 + 4n^2) * (1.3m^2 + 4n^2) = 1.69m^4 + 2.6m^2n^2 + 16n^4

2. (2.5a^2 + 4b)^2 = (2.5a^2 + 4b) * (2.5a^2 + 4b) = 6.25a^4 + 20a^2b + 16b^2

3. (5/2p - 0.5q^3)^2 = (5/2p - 0.5q^3) * (5/2p - 0.5q^3) = 6.25/4p^2 - 2.5pq^3 + 0.25q^6

4. (2.4m^3 - 3/4t)^2 = (2.4m^3 - 3/4t) * (2.4m^3 - 3/4t) = 5.76m^6 - 4.32m^3t + 0.5625t^2

5. (7/4 + 0.6b^4)^3 = (7/4 + 0.6b^4) * (7/4 + 0.6b^4) * (7/4 + 0.6b^4) = 3.433/16 + 6.195b^4 + 4.26b^8 + 3.024b^12

6. (3/8a - 2/3b^4)^2 = (3/8a - 2/3b^4) * (3/8a - 2/3b^4) = 9/64a^2 - 3/4ab^4 + 4/9b^8
