Question

ex 6 repede va rog dau coroana​

Answer 1

Avem urmatorii radicali:

$\sqrt{9} =3\\\\\sqrt{27} =3\sqrt{3} \\\\\sqrt{63} =3\sqrt{7} \\\\\sqrt{50} =5\sqrt{2}$

$\sqrt{20} =2\sqrt{5}$

x+y

2√3-3

√7-√7=0

-5√2+0√5=-5√2

y+x

-3+2√3

-√7+√7=0

0√5-5√2=-5√2

(x+y)+z

2√3-3+3√3=5√3-3

√7-√7+3√7=3√7

-5√2+0√5-2√5=-5√2-2√5

x+(y+z)

2√3-3+3√3=5√3-3

√7-√7+3√7=3√7

0√5-2√5-5√2=-2√5-5√2
