Answer 1

Odpowiedź:

a)

∛[(-2)³/125] = -2/5

b)

∛[(-2)^6/(-3)³] = 2²/(-3) = -4/3 = -1 1/3

c)

√(1 9/16) - ∛125/64 = √25/16 - 5/4 = 5/4 - 5/4 = 0

d)

(√121 - ∛125)/(√144 - ∛216) = (11 - 5)/(12 - 6) = 6/6 = 1

e)

∛4/∛15 * ∛10/9 = ∛40/135 = ∛8/27 = 2/3

f)

∛(2 1/2) * ∛1/20 = ∛5/2 * ∛1/20) = ∛(5/2 * 1/20) = ∛1/8 = 1/2

g)

∛0,8 : ∛(1 9/16) = ∛(0,8 : 25/16) = ∛(4/5 * 16/25) = ∛64/125 = 4/5

h)

∛5/6 : ∛1,44 = ∛5/6 : ∛144/100 = ∛(5/6 * 100/144) = ∛(5/3 * 50/144) =

= ∛(5/3 * 25/72) = ∛125/216 = 5/6
