Answer 1

Răspuns:

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
