Va rog sa mă ajuți cu ex 4

Answer 1

Răspuns:

√(5/2) = √5 / √2

√(14/5) = √14 / √5

√1,4 = √(14/10) = √14 / √10

√3,3 = √(33/10) = √33 / √10

√4,2(3) =  √(127/30) = √127 / √30

4,2(3) = (423-42)/90 = 381/90 = 127/30

√2,1(6) = √(65/30) = √65 / √30

2,1(6) = (216-21)/90 = 195/90 = 65/30

√0,41(6) = √(5/13) = √5 / √13

0,41(6) = (416 - 41)/900 = 375/900 = 15/36 = 5/13

√2,8 = √(28/10) = √28 / √10
