Odpowiedź:
a]
(1/7 - 1/3)^0 = 1
b]
(1 1/4)^2 = (5/4)² = 25/16 = 1 9//16
c]
(1/2)^2 = 1/4
d]
(-4)^3/25 - 4/5 + (4/5)^2 = -64/25 - 4/5 + 16/25 = -48/25 - 20/25 = -68/25 =
= -2 28/25
e]
8^2 : 10^2 + (0.6)^2 = (8 : 10)² + 0,6² = (4/5)² + (3/5)² = 16/25 + 9/25 = 25/25 = = 1
f]
5^3 - 4^2 * 2^3 = 5³ - (2²)² * 2³ = 5³ - 2^4 * 2³ = 5³ - 2^7 = 125 - 128 = -3
