¡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
