Answer 2

Răspuns:

a) 2³ + 21 × 3 - 36 ÷ 3

= 8 + 63 - 12 = 71 - 12 = 59

b) 57 ÷ 3 + 13 × 2 - 5²

= 19 + 26 - 25 = 19 + 1 = 20

c) 1³² × 7¹ - 0⁵ × 5⁰ - 4¹ × 10⁰ + 3²⁰⁰³ × 0²⁰⁰³

= 1 × 7 - 0 × 1 - 4 × 1 + 3²⁰⁰³ × 0

= 7 - 0 - 4 + 0 = 7 - 4 = 3

d) 13 × 5 - 3³ + 90 ÷ 5

= 65 - 81 + 18 = -16 + 18 = 2

e) 12² ÷ 6 - 6 ÷ 2 + 3³

= 144 ÷ 6 - 3 + 81

= 24 - 3 + 81 = 21 + 81 = 102

f) 100 - 4³ + 225 ÷ 15 + 18 × 2.017⁰

= 100 - 64 + 15 + 18 × 1

= 36 + 15 + 18 = 51 + 18 = 69

g) 5² - 15⁰ + 3 × 10

= 25 - 1 + 30 = 24 + 30 = 54

h) 5³ + 5³ ÷ 5² - 10²

$= {5}^{3} + {5}^{3 - 2} - 10 {}^{2} = 5 {}^{3} + 5 - 10 {}^{2}$

= 125 + 5 - 100 = 130 - 100 = 30

i) 4² + 6 × 3 - 84 ÷ 7 + 7² - 2⁴ + 8⁰

= 16 + 18 - 12 + 49 - 16 + 1

= 34 - 12 + 49 - 16 + 1

= 22 + 49 - 16 + 1

= 71 - 16 + 1 = 55 + 1 = 56
