a)

5^8 * 2^5 = 5³(5 * 2)^5 = 125 * 10^5 = 1,25 * 10^7

b)

0,2³ * 5^7 = 5^4(0,2 * 5)³ = 625 * 1³ = 625

c)

(3/4)^6 : (9/16)^5 = 3/4(3/4 * 16/9)^5 = 3/4 * (4/3)^5 = (4/3)^-1 * (4/3)^5 = (4/3)^4

6.

a)

(5²)^5 * (5^4)³ = 5^10 * 5^12 = 5^22

b)

(7^8)³ : (7^5)^4 = 7^24 : 7^20 = 7^4

c)

[(1/2)³]^4 * [(1/2)^5]^5 = (1/2)^12 * (1/2)^25 = (1/2)^37

7.

[(2^4)² * 2]/2^8 = (2^8 * 2)/2^8 = 2^9 : 2^8 = 2
