Answer 1

Resposta:

Explicação passo a passo:

a) 32 +42 + 52 = 126

= 126 (adição)

b) 92 - 100 - 26= -34

= -34

c) 27: 33 x 23 +1= 19,81

27: 33= 0,81

0,81 X 23 = 18,81

18,81 + 1 = 19,81

d) 102 : 4 - 3 x 23 - 120= - 163,5

102 : 4 = 25,5

3 x 23 = 69

25,5 - 69 - 120= - 163,5

e) 62 : 32 - 102 : 50= - 0,11

62 : 32 = 1,93

102 : 50 = 2,04

1,93 - 2,04 = - 0,11

f) ( 72 + 1) 2 : (32 + 42 ) = 1, 97

(72 + 1)= 73

73 . 2 = 146

(32 + 42) = 74

146 : 74 = 1,97

g) 5² : ( 5 +1 -1)+ 4 x 2 = 13

5²= 25

( 5 + 1 - 1) = 5

4 X 2 = 8

25 : 5 = 5

5 + 8 = 13

h) (3 +1)² +2 x 5 - 10⁰ = 25

(3 + 1)= 4

4 ² = 16

2 X 5 = 10

10⁰= 1

16 + 10 - 1 = 25

i) 3²: ( 4 – 1) + 3 x 2² = 15

3²= 9

( 4 - 1) = 3

2²= 4

3 X 4 = 12

9 : 3 = 3

3 + 12 = 15

j) 70 –[ 5 x (2² : 4) + 3²] = 56

[ 5 x 1 + 9] = 14

70 - 14 = 56

k) ( 7 + 4) x ( 3² - 2³) = 11

( 7 + 4 ) = 11

(9 - 8) = 1

11 x 1 = 11

l) 5² + 2³ - 2 x (3 + 9) = 9

5² = 25

2³= 8

(3 + 9) = 12

2 x 12= 24

25 + 8 - 24= 9

m) 6² : 3² + 4 x 10 – 12 = 32

6²= 36

3² = 9

4 x 10 = 40

36 : 9 = 4

4 + 40 - 12 = 32

n) (7² - 1 ) : 3 + 2 x 5 = 26,33

7² = 49

49 - 1 = 48

2 x 5 = 10

49 : 3 = 16,33

16,33 + 10 = 26,33

o) 4²- 10 + (2³ - 5) = 9

4² = 16

2³ = 8

(8 -5) = 3

16 - 10 +3 = 9

p) 30 – (2 + 1)²+ 2³ = 29

( 2 + 1) = 3

3² = 9

2³ =  8

30 - 9 + 8 = 29

q) 30 + [6² : ( 5 – 3) + 1 ] = 49

6² = 36

( 5- 30) = 2

[36: 2 + 1 ] = 19

30 + 19 = 49

r) 20 – [6 – 4 x( 10 - 3²) + 1] = 17

(10 - 3²) = 1

[ 6 - 4 X 1 + 1 ] = 3

20 - 3 = 17

s) 50 + [ 3³ : ( 1 + 2) + 4 x 3] = 15

( 1 + 2) = 3

3²=9

4 X 3 = 12

[ 9 : 3 + 12] = 15

t) 100 –[ 5² : (10 – 5 ) + 2⁴ x 1 ] = 79

(10-5) = 5

5² = 25

2⁴ = 16

[ 25 : 5 + 16 X 1] =21

100 - 21 = 79

u) [ 4² + ( 5 – 3)³] : ( 9 – 7)³ = 3

( 5 - 3) = 2

2³= 8

( 9- 7 ) = 2

2³= 8

4² = 16

[ 16 + 8] = 24

24 : 8 = 3

v) 7²+ 2 x[(3 + 1)² - 4 x 1³] = 73

7² = 49

( 3+ 1) ² = 16

[ 16 - 4 x 1 ] = 12

49 + 2 x 12= 73

w) 25 + { 3³ : 9 +[ 3² x 5 – 3 x (2³- 5¹)]} =36

( 2³ - 5¹) = 8 - 5 = 3

[ 3 ² x 5 - 3 x 3 ]= 9 x 5 - 3 x 3 = 45 - 9 = 36

x) [( 4² + 2 . 3²) + ( 16 : 8)² - 35]² + 1¹⁰ - 10⁰= 9

( 4² + 2 x 3²) = 16 + 2 x 9 = 16 + 18 = 34

(16 : 8 )² = 4

[ 34 + 4 - 35] ² = 9

9 + 1 - 1 = 9

y) ( 8 : 2) . 4 + {[(3² - 2³) . 2⁴ - 5⁰] . 4¹}= 76

( 8 : 2) = 4

( 3² - 2³) = 9 - 8 =1

[ 1 x 2⁴ - 5⁰] = 1 x 16 - 1 = 15

{ 15 x 4} = 60

4 x 4 + 60 = 76

z) 25 + { 3³ : 9 +[ 3² x 5 – 3 x (2³- 5¹)]}= 54

( 2³- 5¹) = 8 - 5 = 3

[ 3² x 5 - 3 x 3 ] = 9 x 5 - 3 x 3 = 45 - 9 = 36

{ 3³ : 9 + 36} = 27 : 9 + 26 = 29

25 + 29 = 54
