dau coroana!!

Answer 1

Fiecare operatie pe rand:

3$\frac{1}{2}$ - 0,5 = $\frac{7}{2}$ - $\frac{1}{2}$ = $\frac{7-1}{2}$ = $\frac{6}{2}$ = 3

$3^{3}$ = 27

27:(3,(3) + 5,(6) ) = 27:(3$\frac{3}{9}$ + 5$\frac{6}{9}$ ) = 27:(3$\frac{1}{3}$ + 5 $\frac{2}{3}$ = 27: ($\frac{10+17}{3}$ = 27:($\frac{27}{3}$ = 27:9 = 3

dar mai intai scrii exercitiul complet:
[(3$\frac{1}{2}$ - 0,5)^3] : ( 3,(3) + 5,(6))
