Answer 1

Ответ:

7::1) x^(12+3) = x^15;

2) (x - x^21) = x^(1-21) = x^(-20);

3) y * y^3 * y^1 = y^(1+3+1) = y^5;

4) (a+b)^(3+3) = (a+b)^6;

5) (x-2y) * (x-2y)^2 = (x-2y) * (x-2y)^(2+1) = (x-2y) * (x-2y)^3;

6) (xy) * (xy) = (xy)^(1+1)=(xy)^2

8::1) x^10 / (x^2) = x^(10 - 2) = x^8

2) m^32 / (m^8) = m^(32 - 8) = m^24

3) (xy)^5 / ((xy)^5) = 1 (поскольку (xy)^5 поделено на (xy)^5 равно 1)

4) (a + 4)^7 / ((a + 4)^2) = (a + 4)^(7 - 2) = (a + 4)^5

5) p^41 / p = p^(41 - 1) = p^40

6) (3b - 1)^5 / (3b - 1) = (3b - 1)^(5 - 1) = (3b - 1)^4

9::

1) (x^5)^20 = x^(5*20) = x^100

2) (x^9)^2 * (x^2)^6 = x^(9*2) * x^(2*6) = x^18 * x^12 = x^30

3) (x^2)^31 = x^(2*31) = x^62

4) (x^3)^4 * (x^4)^3 = x^(3*4) * x^(4*3) = x^12 * x^12 = x^24

11::1) (4x + 2x) - (2x³ + 3x) = 6x - (2x³ + 3x)

2) (6a - 5a²) - (3a² - 4a) = 6a - 5a² - 3a² + 4a = 6a - 8a²

3) (862 - 56) - (4b - 362) = 806 - 4b + 362 = 1168 - 4b

4) (8 - 3y³) - (5 - 3y³) = 8 - 3y³ - 5 + 3y³ = 3
