Aducem la o forma mai simpla facand simplificari si obtinem
18/5v3-3/v3+1/v3-(4/3v2+3/2v2-10/3v2)=18/5v3-2/v3+6/3v2-3/2v2
Aducem la ac numitor si avem
18-10/5v3+12-9/6v2=8/5v3+3/6v2=8/5v3+1/2v2
La pct b) aducem la ac numitor care este 6V3 respectiv 30v2 si dupa ce facem calculele obtinem
3/2v3-2/3v2
