a) (0,035)^7 : (0,005)^7 = (0,035 : 0,005)^7 = 7^7
b) (2/3)^5 * (4,5)^5 = (2/3 * 4 1/2)^5 = (2/3 * 9/2)^5 = 3^5
c) 15^6 * 15^4 / 3² * 3^8 = 15^10/3^10 = (15/3)^10 = 5^10
d) (3^4 * 3^5)² : 3^11 = (3^9)²/3^11 = 3^18/3^11 = 3^7
e) (2√5)²- (∛7)³ = 4*5 - 7 = 20 - 7 = 13
f) √1/2 : √1/18 = √(1/2 * 18) = √9 = 3
g) ∛3/16 : ∛4/9 = ∛(3/16 * 9/4) = ∛27/64 = 3/4
h) ∛(√4 - √100) = ∛(2 - 10) = ∛-8 = -2
