Răspuns:

3. x= ( $\frac{2}{2\sqrt{3} }$ + $\frac{9}{3\sqrt{3} }$ + $\frac{6}{6\sqrt{3} }$) x $\sqrt{3}$ = ($\frac{1}{\sqrt{3} }$ + $\frac{3}{\sqrt{3} }$ + $\frac{1}{\sqrt{3} }$) x $\sqrt{3}$ = 1+3+1 = 5

R: x=5

y = (5^6)^3 x 25^3 : 125^8= 5^18 x (5^2)^3 : (5^3)^8

  = 5^18 x 5^6 : 5^24

  = 5^24 : 5^24= 1

y=1

4. x ori y = 5 ori 1 = 5

   5 este cuprins intre 2^2=4 si 3^3=9 rezulta numar prim
