Răspuns:
a) (-2^3)+5x((-1)^2021+(-1)^2020
-8+5x(-1)+(-1)=-8+(-5)+(-1)=-13+(-1)=14
b) (-2)^101:2^99-10x(-3-3x((-3)^5: 3^4-2))
-2^2-10x(-3-3x(-3)^1-2)
4-10x(-3-3x(-3)-2)
4-10x(-3-(-9)-2)
4-10x6-2
4-60-2
4-58
= -54
c) 5^3x(14x(-1)^35+(-1)^34-5x(5-4:(-2))):2^3
5^3x(14x(-1)+(-1)-5x(5-(-2))):2^3
5^3x(-14+(-1)-5x7:2^3
5^3x(-15)-35:2^3
5^3x3x5-35:2^3
(125x15-35):2^3
1840:8=230
