Question

ordonati crescator numerele:radical 9;|-6,(2)|;-radical 20;3,27;-4,5;|4,28|;7;-1

Answer 1

-4,5 < 4,47 < -1< 6,2 < 3 < 4,28 < 7,27

Answer 2

$\sqrt{9} = \sqrt{3} ^{2} =3$
$|-6,(2)|=|- \frac{62-2}{9} |=|- \frac{60}{9} |=|- \frac{3}{20}|= \frac{3}{20}$
$\frac{3}{20}= \frac{15}{100} =0,15$
$-\sqrt{20} =-4,472135...$
3
27
-4,5
|4,28|=4,28
7
-1
Ordine: -4.5,$\sqrt{20}$,-1,|-6.(2)|,$\sqrt{9}$,4.28,7,27
