8/34
a) 1/2^-9 : 2^8 = 2^9 : 2^8 = 2
b) 2^18 * 2^-9/2^5 = 2^4 = 16
c) 5^-4 : 5^-4 - (5/3)^6 * (5/3)^-7 = 1 - 3/5 = 2/5
d) 7^3/3^6 : 7^3/3^3 * 1/3^-6 = 1/3^3 * 1/3^-6 = (1/3) ^ -3 = 3^3 = 27
e)(16/125)^2 : (8/75)^3 = 2^8/5^6 : 2^9/5^6 * 1/27 = 2^-1/1 * 1/27 = 2^-1/27 = (2/27)^-1 = 27/2 = 13 1/2          dobra juz jest dobrze
f) (6/5)^3 * (9/7)^3 * 3^-8/7^-4 * (6/5)^-3 = 1 * 3^6/7^3 * 3^-8/7^-4 = 1* ( 3^2/7)^-1 = 7/9  Prosze gotowe
