i)∛-0,5 · ∛4 / ∛16 =

Answer 1

a)√2 · √4¹/₂ =  √4 = 2

b)√2²/₃ : √²/₃ = √2 2/3 * √3/2 =  √2

c)√6,4 : √10 =√6,4 * √1/10 =√61/10 *  √1/10 = √64/100 = 8/10 = 4/5

d)∛10 · ∛0,1 =∛1 = 1

e)∛2²/₃ · ∛¹/₉ =∛8/3 * ∛1/9 = ∛8/27 = 2/3

f)∛2,7 : ∛100 =∛27/10 *∛1/100 =∛27/1000 = 3/10

g)∛-9 · ∛3 = ∛-27 = - 3

h)∛128 : ∛-2 = ∛128 * ∛-1/2 =∛64 = 4

i)∛-0,5 · ∛4 / ∛16 =∛-0,5 * ∛1/4 = ∛-0,5 * ∛0,25 = ∛-0,125 = -0,5
