Odpowiedź:
Szczegółowe wyjaśnienie:
Zad. 3
3^4x3^6/(3^3)^3 = 3^10/3^9 = 3^10-9 = 3^1 = 3
Zad. 2
(0.6x5)^3 = 3^3 = 27
---
(2/9:4/9)^4 = (2/9x9/4)^4 = (2x1/4)^4 = (1/2)^4 = 1/16
---
(5/7x2 4/5)^5 = (5/7x14/5)^5 = (1/7x14)^5 = 2^5 = 32
---
6.4^6:(-8^2/10)^6 = (6.4:(-8^2/10))^6 = (32/5:(-8^2/10))^6 = (-32/5:8^2/10)^6 =
= (-2^5/5x10/8^2)^6 = (-2^5/5x10/2^6)^6 = (-2^5:2/2^6)^6 = (-2/2)^6 = (-1)^6 = 1
Proszę bardzo :D
