Odpowiedź:
a)
(5^4 + 5^4 + 5^4 + 5^4 + 5^4)/5³ = 5 * 5^4/5³ = 5^5 : 5³ = 5² = 25
b)
0,25^4 * 28^6/7^6 = (0,5²)^4 * (28/7)^6 = 0,5^8 * 4^6 = (1/2)^8 * (2²)^6 =
= 2^-8 * 2^12 = 2^4 = 16
c)
(2^6 * 5^12 * 7^6)/3,5^6 : 10^10 = 2^6 * 5^12 * (7 : 3,5)^6 : 10^10 =
= 2^6 * 5^12 * 2^6 : 10^10 = 2^12 * 5^12 : 10^10 = (2 * 5)^12 : 10^10 =
= 10^12 : 10^10 = 10² = 100
