b) 33 + 23 − 8 ∙ 5

c) 378 − 32 ∙ √400 ÷ √25

d) {[(9 + 3 ⋅ 2)2 − 43] ÷ 4 + (2 − 1)7} ÷ (3 − 4 ⋅ 2)

e) [−2 ∙ (−32)2+ 22] ÷ (−2)2

f)−(−2)2− √27 3(−3∙5)0−2

Answer 1

Letra F não consegui, espero ter ajudado em algo.

Explicação passo-a-passo:

a) 174 + 27 ∙ 3 − 79

174+81-79

176

b) 33 + 23 − 8 ∙ 5

33+23-40

16

c) 378 − 32 ∙ √400 ÷ √25

378-32.20 : 5

378 - 640 : 5

378- 128

250

d) {[(9 + 3 ⋅ 2)2 − 43] ÷ 4 + (2 − 1)7} ÷ (3 − 4 ⋅ 2)

{[15.2-43] : 4+2.7} : -5

{[30-43]:4+2.7}:-5

{-13:4+14}:-5

{-3,25+14}: -5

10,75:-5

-2,15

e) [−2 ∙ (−32)2+ 22] ÷ (−2)2

[64.2+22] :-4

[128+22] : -4

150: -4

-37,5
