Answer 1

Odpowiedź:

zadanie 1:

2^3 = 2 x 2 x 2 = 8

6^2 = 6 x 6 = 36

(-4)^2 = (-4) x (-4) = 16

(-2)^3 = (-2) x (-2) x (-2) = -8

(1/3)^3 = 1/3 x 1/3 x 1/3 = 1/27

(2/5)^4 = (2/5) x (2/5) x (2/5) x (2/5) = 16/625

(5/4)^2 = (5/4) x (5/4) = 25/20 = 5/4

(2/10)^3 = (2/10) x (2/10) x (2/10) = 8/1000 = 4/500

zadanie 2:

(1 1/4)^3 = (5/4)^3 = 5/4 x 5/4x 5/4 = 125/64 = 1 61/64

(2 2/3)^2 = (8/3)^2 = 8/3 x 8/3 = 64/9 = 7 1/9

(-1 1/2)^3 = (-3/2)^3 = (-3/2) x (-3/2) x (-3/2) = (-27/8) = (-3 3/8)

(-2 2/5)^2 = (-12/5)^2 = (-12/5) x (-12/5) = 144/25 = 5 19/25
