Question

3) Comparati numerele. a) -5 şi 5, 7 b) - 1,5 şi -1,4 c) - radical din 5 si - 2,23​

Answer 1

Răspuns:

$\green{\bf a)~~~ -5~ < ~5,7}$

$\blue{\bf b)~~~ 1,5~ > ~1,4}$

$\bf c)~~-\sqrt{5} ~~\boxed{~}~-2,23~~~\bigg|^{2}$

$\bf (-\sqrt{5})^{2} ~~\boxed{~}~~(-2,23)^{2}$

$\bf (\sqrt{5})^{2} ~~\boxed{~}~~(2,23)^{2}$

$\pink{\boxed{\bf 5~~~>~~4,9729}}$
