Odpowiedź:
2.
a)
(2/3)^4 * (2/3)^7 = (2/3)^11
b)
(-3)^5 * (-3)² * (-3)^7 = (-3)^14
c)
(1/7)^6 * (1/7)² : (1/7)³ = (1/7)^5
d)
5^9 : (5^6 * 5²) = 5
e)
6^4 * 6^8 : (6^6 * 6) = 6^5
f)
(-2/9)^8 : (-2/9)^5 * (-2/9)^7 = (-2/9)^10
3.
a)
2^5 * 2³/2^8 = 2^8 : 2^8 = 2^0 = 1
b)
3^4 * 3³/(3² * 3^0) = 3^7 : 3² = 3^5
c)
9^5 * 9²/(9 * 9^4) = 9^7 : 9^5 = 9²
d)
5^11/(5^6 * 5^6) = 5^11 : 5^12 = 5^-1
