Mi fate queste due espressioni, per favore???

[mary light ^.^]

1. {[(4/9-1/3)°-(3/5-1/3)°*(5/3)°+(1/2)]: (-17/27)+3/4}°

2. [(-9/7)alla terza)*(1+2/5)alla terza : (1+4/5)alla terza] : [3 alla -3 * (-1/3) alla -2 + (+1/2)alla terza * (-2/5) alla terza : (-1/5)°]

°= alla seconda
*= segno della moltiplicazione

Se me le fate tt e 2,beh, grz 1000=)))
