¡Hola!

Las respuestas a tus preguntas son:

e) = -206

d) = 44

€) = 36

D) = -2020

Procedimiento:

e) Desarrollamos:

(5−2×4)−5×(−2)×(−5)+(5−7)×(23+52)+3×(−1)

5−8−5×−2×−5−2×(23+52)+3×−1

5−8−5×−2×−5−2×75+3×−1

5−8−(−10×−5)−2×75+3×−1

5−8−50−2×75+3×−1

5−8−50−150+3×−1

5−8−50−150−3

−3−50−150−3

−53−150−3

−203−3

−206

d) Desarrollamos:

(6×5−3)×2−(3−3×2)+(5×2−12)+1+(−6)×2

(30−3)×2−(3−3×2)+5×2−12+1−6×2

27×2−(3−3×2)+5×2−12+1−6×2

27×2−(3−6)+5×2−12+1−6×2

27×2−(−3)+5×2−12+1−6×2

54−(−3)+5×2−12+1−6×2

54−(−3)+10−12+1−6×2

54−(−3)+10−12+1−12

54+3+10−12+1−12

57+10−12+1−12

67−12+1−12

55+1−12

56−12

44

€) Desarrollamos:

(5+2×(−4))×(−3)−(5×(−4)+(−6))−(−1)

(5−8)×−3−(5×−4−6)−(−1)

−3×−3−(5×−4−6)−(−1)

−3×−3−(−20−6)−(−1)

−3×−3−(−26)−(−1)

9−(−26)−(−1)

9+26+1

35+1

36

D) Desarrollamos:

2×(−5)×(−1)+8×(−4)−20+(−1)×1932−10×(−1)+7×(−8)

10+8×−4−20−1×1932−10×−1+7×−8

10−32−20−1×1932−10×−1+7×−8

10−32−20−1932−10×−1+7×−8

10−32−20−1932−(−10)+7×−8

10−32−20−1932−(−10)−56

10−32−20−1932+10−56

−22−20−1932+10−56

−42−1932+10−56

−1974+10−56

−1964−56

−2020

Espero haberte ayudado.

¡Saludos!.
