b)2la puterea 3*[145:(-29)+13-19]+(-2la puterea 4)*(-5);
c)26+70:(-5)+[(-3)*(-2)*(-5)+15:(-3)+1+75:(-3)]:-59)

va rog cine ma poate ajuta e urgent!!! ofer coroana multumesc

Answer 1

a)[-180:(-2²)+35-25:(-5)]:17=
=(-180:(-4)+35+5):17=
=(+45+40):17=
=85/17=5

b)2³*[145:(-29)+13-19]+(-2⁴)*(-5)=
=2³*(-5+13-19)+80=
=2³*(-11)+80=
=-88+88=-8

c)26+70:(-5)+[(-3)*(-2)*(-5)+15:(-3)+1+75:(-3)]:(-59)=
=26-14+(-30-5+1-25):(-59)=
=12+(-59):(-59)=
=12+1=13
