cum se rez:23 la puterea a 6totul la 13×23la puterea a 4 totul la 15?17la puterea12totul la8:17 la puterea13 totul la 5​

Answer 1

(23^6)^13 = 23^(6*13) = 23^78

(23^4)^15 = 23^(4*15) = 23^60

(23^6)^13 * (23^4)^15 = 23^78 * 23^60 = 23^(78+60) = 23^138

(17^12)^8 = 17^(12*8) = 17^96

(17^13)^5 = 17^(13*5) = 17^65

(17^12)^8 : (17^13)^5 = 17^96 : 17^65 = 17^(96-65) = 17^31
