Proszę pomóżcie, mam to zadane na jutro. Z góry dzięki :)

Answer 1

a) √0 = 0,

√1 = 1,

√4 = 2,

√16 = 4,

√25 = 5,

√9 = 3,

√100 = 10,

√400 = 20,

√121 = 11

b) √1/4 = 1/2,

√1 11/25 = √36/25 = 6/5 = 1 1/5,

√2 14/25 = √64/25 =  8/5 = 1 3/5,

√16/49 = 4/7 

√81/196 = 9/14,

√0,04 = 0,2,

√0,0001 = 0,01,

√6,25 = 2,5

 

c) ∛0 = 0,

∛1 = 1,

∛27 = 3,

∛125 = 5,

∛64 = 4,

∛8 = 2,

∛1000 = 10

d) ∛1/8 = 1/2,

∛1/125 = 1/5,

∛2 10/27 = ∛64/27 = 4/3 = 1 1/3,

∛8/27 = 2/3,

∛4 17/27 = ∛125/27 = 5/3 = 1 2/3,

∛0,008 = 0,2,

∛0,125 = 0,5
