Answer 1

Odpowiedź:

Szczegółowe wyjaśnienie:

10.

a)

(1 1/7)² = (8/7)² = 64/49 = 1 i 15/49

b)

(-1 2/3)³ = (-5/3)³ = -125/8 = -15 i 5/8

c)

-1,1² = -1,21

d)

(-4/9)⁰ = 1

11.

a)

(1,5)⁵ : (1,5)³ = (1,5)² = 2,25 = 2 i 25/100 = 2 i 1/4

b)

(2/3)⁷ * 3⁷ = (2/3 * 3)⁷ = 2⁷ = 128

c)

(2/9)⁶ * (4 1/2)⁷ = (2/9)⁶ * (4 1/2)⁶ * 4 1/2 = (2/9)⁶ * (9/2)⁶ * 9/2 = (2/9 * 9/2)⁶ * 9/2 = 1⁶ * 4 1/2 = 1 * 4 1/2 = 4 i 1/2

d)

(8² * 2³) / 2⁸ = [(2³)² * 2³] / 2⁸ = (2⁶ * 2³) / 2⁸ = 2⁹ / 2⁸ = 2¹ = 2
