Odpowiedź:
a)
(1/7 - 1/3)^0 = 1
b)
(1 1/4)² * 10³ - (-2)³ = (5/4)² * 1000 - (-8) = 25/16 * 1000 + 8 = 25/2 * 125 + 8 =
= 3125/2 + 8 = 1562,5 + 8 = 1570,5
c)
(1/2)² + (1/3)² = 1/4 + 1/9 = 9/36 + 4/36 = 13/36
d)
(-4)³/25 - 4/5 + (-4/5)² = -64/25 - 20/25 + 16/25 = -64/25 - 4/25 = -68/25 =
= 2,72
e)
8² : 10² + 0,6² = 64 : 100 + 0,36 = 0,64 + 0,36 = 1
f)
5³ - 4² * 2³ = 125 - 16 * 8 = 125 -128 = -3
