Odpowiedź:
1.
a)
-(-1/4)³ + (1/4)² = -(-1/64) + 1/16 = 1/64 + 4/64 = 5/64
b)
(5/6)² - 5²/6 + 5/6² = 25/36 - 25/6 + 5/36 = 30/36 - 4 1/6 = 5/6 - 3 7/6 = -3 2/6 =
= -3 1/3
c)
10 * (-0,4)³ * 10³ = 10 * (-0,4 * 10)³ = 10 * (-4)³ = -10 * 64 = -640
d)
8² * 1/8 - (-1/8)^0 - (-8)² = 8² * 8^-1 - 1 - 64 = 8 - 65 = -57
2.
[5^13 : (5^6 * 5²)]/5³ = (5^13 : 5^8)/5³ = 5^5 : 5³ = 5² = 25
