Answer 1

Resposta:Segue as contas abaixo na explicação

Explicação passo-a-passo:

a) 30 + [62: (5 – 3) + 1 ]

    30+[62:2+1]

    30+[31+1]

    30+32

       62

b)20 - [6 – 4 x( 10 - 32) + 1]

   20-[6-4.(-22)+1]

   20-[6+88+1]

   20-95

   -75

c) 50 + [ 33 : (1 + 2) + 4 x 3]

   50+[33:3+12]

   50+[11+12]

   50+23

      73

d) 100 - [ 52 : (10 -5 ) + 24 x 1 ]

    100-[52:5+21]

    100-[10,4+21]

    100-31,40

      68,60

e) [ 42 + ( 5 – 3)3] : (9 - 7)3

   [42+(2)^3]:(2)^3

   [42+8]:8

      50:8

      6,25

f) 72+ 2 x[(3 + 1)2 - 4 x 13]

   72+2.[(4)^2-52]

   72+2.[16-52]

   72+2.[-36]

   72-72

       0

g) 25 +{ 33 : 9 +[ 32 x 5 – 3 x (23- 5')]}

   25+{11+[160-3.18]}

   25+{11+[160-54]}

   25+{11+106}

   25+117

      142
