Explicação passo-a-passo:
11)
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 + 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
12)
a)
5² : (5 + 1 - 1) + 4 x 2
= 5² : (6 - 1) + 4 x 2
= 5² : 5 + 4 x 2
= 25 : 5 + 4 x 2
= 5 + 8
= 13
b)
(3 + 1)² + 2 x 5 - 10⁰
= 4² + 2 x 5 - 10⁰
= 16 + 2 x 5 - 1
= 16 + 10 - 1
= 26 - 1
= 25
c)
3² : (4 - 1) + 3 x 2²
= 3² : 3 + 3 x 2²
= 9 : 3 + 3 x 4
= 3 + 12
= 15
d)
70 - [5 x (2² : 4) + 3²]
= 70 - [5 x (4 : 4) + 3²]
= 70 - [5 x 1 + 3²]
= 70 - [5 x 1 + 9]
= 70 - [5 + 9]
=70 - 14
= 56
e)
(7 + 4) x (3² - 2³)
= 11 x (9 - 8)
= 11 x 1
= 11
f)
5² + 2³ - 2 x (3 + 9)
= 5² + 2³ - 2 x 12
= 25 + 8 - 2 x 12
= 25 + 8 - 24
= 33 - 24
= 9
g)
6² : 3² + 4 x 10 - 12
= 36 : 9 + 4 x 10 - 12
= 4 + 40 - 12
= 44 - 12
= 32
h)
(7² - 1) : 3 + 2 x 5
= (49 - 1) : 3 + 2 x 5
= 48 : 3 + 2 x 5
= 16 + 10
= 26
