d)25 do potęgi -2 / 5 do potęgi -4 =
Prosze o szybkie i poprawde odp

Answer 1

a) 2^-2 * (1/4)^-2 =(1/2)^2*4^2 = 1/4 * 16 = 4
b)(3/7)^-3 : (9/49)^-3 =(7/3)^3 : (49/9)^3 = 343/27 : 117649/729 = 343/27 * 729/117649 = 1 * 27/343 = 27/343
c)(3/5)^-6 * (5/3)^-6 = (5/3)^6 * (5/3)^-6 = (5/3)^0 = 1
d)25^-2 / 5^-4 = 1/625 : 1/625 = 1/625 * 625/1 = 1
