Answer 1

Explicação passo-a-passo:

1)

a)

3² + 5

= 9 + 5

= 14

b)

3 + 5²

= 3 + 25

= 28

c)

3² + 5²

= 9 + 25

= 34

d)

5² - 3²

= 25 - 9

= 16

e)

18 - 7⁰

= 18 - 1

= 17

f)

5³ - 2²

= 125 - 4

= 121

g)

10 + 10²

= 10 + 100

= 110

h)

10³ - 10²

= 1000 - 100

= 900

i)

10³ - 1¹

= 1000 - 1

= 999

2)

a)

2³ x 5 + 3²

= 8 x 5 + 9

= 40 + 9

= 49

b)

70⁰+ 0⁷⁰ - 1

= 1 + 0 - 1

= 1 - 1

= 0

c)

3 x 7¹ - 4 x 5⁰

= 3 x 7 - 4 x 1

= 21 - 4

= 17

d)

3⁴ - 2⁴ : 8 - 3 x 4

= 81 - 16 : 8 - 3 x 4

= 81 - 2 - 12

= 79 - 12

= 67

e)

5² + 3 x 2 - 4

= 25 + 3 x 2 - 4

= 25 + 6 - 4

= 31 - 4

= 27

f)

5 x 2² + 3 - 8

= 5 x 4 + 3 - 8

= 20 + 3 - 8

= 23 - 8

= 15

g)

5² - 3 x 2² - 1

= 25 - 3 x 4 - 1

= 25 - 12 - 1

= 13 - 1

= 12

h)

16 : 2 - 1 + 7²

= 16 : 2 - 1 + 49

= 8 - 1 + 49

= 7 + 49

= 56
