Answer 1

Explicação passo-a-passo:

r) 25-[10 + (7 - 4)] =

25-[10+(3)]=

25-[13]=

12

s) 32+ [10-(9-4)+8] =

32+[10-(5)+8]=

32+[5+8]=

32+[13]=

45

t) 45-[12-4+(2+1)] =

45-[12-4+(3)]=

45-[12-7]=

45-[5]=

40

u) 5² + 2³ - 2 x (3 + 9) =

25+8-2.(12)=

25+8-24=

33-24=

9

v) 6² : 3² + 4 x 10 – 12 =

36:9+4.10-12=

4+40-12=

44-12=

32

w)(7² - 1 ) : 3 + 2 x 5 =

(49-1):3+2.5=

(48):3+2.5=

16+10=

26

x) 4²- 10 + (2³ - 5) =

16-10+(8-5)=

16-10+(3)=

16-13=

3

y) 30 – (2 + 1)²+ 2³ =

30-(3)^2+2^3=

30-9+8=

21+8=

29

z) [ 4² + ( 5 – 3)³] : ( 9 – 7)³ =

[16+(2)^3]:(2)^3=

[16+8]:8=

[24]:8=

3
