Explicație pas cu pas:
a=(-1)^2+(-1)^3+(-1)^4+(-1)^2×3×4=
a=1+(-1)+1+1=
a=0+1+1=2
b=-3^3 +(-3)^7÷81-(-4)^3
b=(-3)^3+7÷81-(-4)^3
b=(-3)^10÷81-(-4)^3
b=59049÷81-(-4)^3
b=729-(-4)^3
b=729-(-64)
b=793
c=+8-(-2×3)^2+[(-2)^3]^2÷(-3^2×7-1)=
c=8-(-2×3)^2+(-8)^2÷(-3^2×7-1)=
c=8-(-2×3)^2×64÷(-3^2×7-1)=
c=8-(-6)^2×64÷(9×7-1)=
c=8-36×64÷(63-1)=
c=8-36×64÷62=
c=8-2304÷62=
c=8-371612903226=
c=-317612903218
b,a,c
