Explicație pas cu pas:

5$\sqrt{3}$ + 3(4$\sqrt{2}$ + 4(3$\sqrt{3}$ +2($\sqrt{3}$ - 3$\sqrt{2}$))) :20

1) 2($\sqrt{3}$ - 3$\sqrt{2}$ = 2$\sqrt{3}$ - 6$\sqrt{2}$

2) 3$\sqrt{3}$ + 2$\sqrt{3}$ - 6$\sqrt{2}$ = 5$\sqrt{3}$ - 6$\sqrt{2}$

3) 4 (5$\sqrt{3}$ - 6$\sqrt{2}$) = 20$\sqrt{3}$ - 24$\sqrt{2}$

4) 4$\sqrt{2}$ + 20$\sqrt{3}$ - 24$\sqrt{2}$ = 20$\sqrt{3}$ - 20$\sqrt{2}$

5) 3( 20$\sqrt{3}$ - 20$\sqrt{2}$) = 60$\sqrt{3}$ - 60$\sqrt{2}$

6) (60$\sqrt{3}$ - 60$\sqrt{2}$ ) : 20 = 3$\sqrt{3}$ - 3$\sqrt{2}$

7) 5$\sqrt{3}$ + 3$\sqrt{3}$ - 3$\sqrt{2}$ = 8$\sqrt{3}$ - 3$\sqrt{2}$
