Question

Resolva as expressões:
a)–7² + √36 + (+8–6)²
b) (–1–3)² – (√1+2)³
c) –5.(–√9+1)² – (1–4)³
d) (–5)² + [(–1)⁸ – (–3)³ : (+9) – (+2)⁵] ​

Answer 1

Explicação passo-a-passo:

a) - 49 + 6 + ( +2)²=

- 49 +6 + 4=

-49 +10=

- 39

b) ( - 4)² - ( 1+2)³=

+ 16 - (+3)³=

16 - (+27)=

16 - 27=

- 11

c) - 5 . (- 3+1)² - (-3)³=

- 5 . ( -2)² - (-27)=

- 5 . (+4) +27=

- 20 +27=

+7

d) (+25) + [ (+1) - (-27) : (+9) - (+32)]=

25 + [ 1 - ( - 3) - 32]=

25 + [ 1 +3 - 32]=

25 + [ 4 - 32]=

25 + [ - 28]=

25 - 28=

- 3

Answer 2

Explicação passo-a-passo:

Resolva as expressões:

a)–7² + √36 + (+8–6)²=

49+6+(2)²=

49+6+4=

55+4=

59

b) (–1–3)² – (√1+2)³=

(-4)²-(1+2)³=

16-(3)³=

16-27=

-11

c) –5.(–√9+1)² – (1–4)³=

-5.(-3+1)²-(-3)³=

-5.(-2)²-(-27)=

-5.4-(-27)=

-20-(-27)=

7

d) (–5)² + [(–1)⁸ – (–3)³ : (+9) – (+2)⁵] =

25+[1-(-27):(+9)-(32)]=

25+[1-(-3)-(32)]=

25+[1-(-35)]=

25+[36]=
