Question

a) (-2^3) + 5×[(-1)^2021 + (-1)^2020 +2×(-2+2×3)];
b) (-2)^101: 2^99 - 10×{-3 -3×[(-3)^5: 3^4 – 2]};
c) 5^3× {14×(-1)^35 + (-1)^34 - 5×[5 - 4: (-2)]}: 2^3;​
Dau coroana plsssss​

Answer 1

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
