PRIMO ESERCIZIO:
= Rt2 x (Rt2)/2 - Rt3 x (-(Rt3)/2) - Rt3 + Rt3 - 1/2 =
= 1 + 3/2 - 1/2 =
= 2
SECONDO ESERCIZIO:
= 2 x 1/2 + 3 x 1/2 + Rt3 + 3 x (-Rt3) =
= 1 + 3/2 + Rt3 - 3Rt3 =
= 5/2 - 2Rt3
TERZO ESERCIZIO:
= Rt3 x (Rt3)/2 - 3 x 1/2 - (Rt3)/3 - (Rt3)/3 =
= 3/2 - 3/2 - (2Rt3)/3 =
= - (2Rt3)/3
Ciauuuuuuuuu!! =)
P.S. La 'x' sta per moltiplicazione!! =)
