Answer 1

Explicação passo-a-passo:

9) Resolva as expressões abaixo:

a) 20 (14.6+2³) =

20+(84+8)=

20+(92)=

112

b) (24-3.4): 2+5²:5=

(24-12):2+25:5=

(12):2+5=

6+5=

11

c) 102 : 52 + 5 . 22 – 23 =

1,96+110-23=

111,96-23=

88,96

d) 6² +2.[2³ +2.(32.1³)]- 25.5⁰ =

36+2.[8+2.(32.1)]-25.1=

36+2.[8+2.(32)]-25.1=

36+2.[8+64]-25.1=

36+2.[72]-25.1=

36+144-25=

180-25=

155

e) 55- (√9-√4+ 1)² + (4²+ 3²): 5² + 16 =

55-(3-2+1)²+(16+9):25+16=

55-(1+1)²+(25):25+16=

55-(2)²+1+16=

55-4+17=

51+17=

68

f) [√196-8:2³ - (15-5-√64)] + 4² =

[14-8:8-(10-8)]+16=

[14-1-(2)]+16=

[14-(-1)]+16=

[15]+16=

31
