Answer 2

Resposta:

a) 38

b) 1

c) 5/7

d) 6

e) 6

f) 10

g) 55

h) 283

Explicação:

a)4³-[(2.√100+3.2)]=

64 - ( 2 • 10 + 3 • 2)

64 - ( 20 + 6)

64 - 26 = 38

b)√100-[√49-(6-2.2²)=

10 - [ 7 - ( 6 - 2 • 4)

10 - [ 7 - ( 6 - 8)

10 - [ 7 - ( -2)

10 - [ 7 + 2

10 - 9 = 1

c)10:{2+[(√16+2³)=

10: ( 2+[4 + 8]

10: ( 2+ 12)

10: 14 = 10/14=5/7

d)(5³-√25):(26-√36=

( 125 - 5):(26-6)

120:20 = 6

e)(5³-√25):(26-√36=

( 125 - 5):(26-6)

120:20 = 6

f)2.[6¹-(√100+12):11=

2•[6-(10+12):11

2• 6-22:11

12 - 2 = 10

g){5.[31-√9.7+23]-√144}:(4-1)=

{5•[31 -3•7+23] - 12} : (3)

{5•[31-21+23] - 12} : 3

{5• [33] - 12} : 3

{165} : 3 = 55

h)√16.{3²[(2³-5)√16+1]-√25}=​

4 • {9[(8-5) 4 + 1] - 5}

4• {9[3+4+1] - 5}

4•{ 9 • 8 - 5}

4 • 72 - 5

288 - 5 = 283
