Question

Fie numerele: -6,...​

Answer 1

2,2(5) = (225-22)/90 = 203/90

-2,5 = -25/10 = -5/2

V9 = 3

pi= 3,14....

a 0; V9

b -6, -V5, -1; -2,5

c -6; -1

d sunt toate numerele afara de -V5 si V2

e -6; -1; -2,5; 0; 2/3; 2,2(5); pi ; V9

f -V5; V2

Answer 2

$\it a)\ 0;\ \ \sqrt9=3.\\ \\ b)\ -6;\ -\sqrt5;\ -1;\ \ -2,5\\ \\ c)\ -6;\ \ -1.\\ \\ d)toate \ sunt \ numere \ reale.\\ \\ e)\ -6;\ -1;\ -2,5;\ 0;\ \dfrac{2}{3};\ 2,2(5);\ \sqrt9\ .\\ \\ f)\ -\sqrt5;\ \ \sqrt2;\ \ \pi\ .$
