prosze o szybką odpowiedz ! ;)
x^y = jakaś liczba podniesiona do jakiejś potęgi
a) (7^6 * 7^3 ) / (7^2)^5 = 7^9 / 7^10 = 7^-1 = 1/7
b) (3^-3 * 27^1/3) / (1/3)^5 =( (1/3)^3 *(1/27)^3 ) / (1/3)^5 = ((1/3)^3 * ((1/3)^3)^3 ) / (1/3)^5 = (1/3)^12 / (1/3)^5= (1/3)^7 = 1/2187
c) 2,5 + (-2/3 - 1,8 *5/6 )^-1 : (-1/3)^3 = 2i1/2 + -2/3 - 9/5 * 5/6) ^-1 :(-1/3)^3 =
5/2+ (-2/3-3/2)^-1 : (-1/27)= 5/2 + (-13/6) ^-1 : (-1/27) = 5/2 + 162/13 = 14i25/26
