Odpowiedź:
1.
a)
2³ = 2 * 2 * 2 = 8
b)
6² = 6 * 6 = 36
c)
(-4)² = -4 * (-4) = 16
d)
(-2)³ = -2 * (-2) * (-2) = -8
e)
(1/3)³ = 1/3 * 1/3 * 1/3 = 1/27
f)
(2/5)^4 = 2/5 * 2/5 * 2/5 * 2/5 = 16/625
g)
(5/4)² = 25/16 = 1 9/16
h)
(-3/7)² = 9/47
i)
(-2/10)³ = -8/1000
2.
a)
(1 1/4)³ = (5/4)³ = 5/4 * 5/4 * 5/4 = 125/64
b)
(2 2/3)² = (8/3)² = 64/9
c)
(-1 1/2)³ = (-3/2)³ = (-3/2) * (-3/2) * (-3/2) = -27/8
d)
(-2 2/5)² = (-12/5)² = 144/25
