Answer 1

5 + 4² -1 = 5 + 16 -1 = 21 - 1 = 20

34 - 6 + 2³ = 34 - 6 + 8 = 34 + 2 = 36

25 - 3² + 19 = 25 - 9 + 19 = 25 + 10 = 35

10² - 3² + 5 = 100 - 9 + 5 = 100 - 4 = 96

11² - 3² + 5 = 121 - 9 + 5 = 121 - 4 = 117

5 x 3² x 4 = 5 x 9 x 4 = 45 x 4 = 180

5 x 2³ + 4² = 5 x 8 + 16 = 40 + 16 = 56

5³ x 2² - 12 = 125 x 4 - 12 = 500 - 12 = 488

(4 + 3)² - 1 = 7² - 1 = 49 - 1 = 48

(5 + 1)² + 10 = 6² + 10 = 36 + 10 = 46

(9 - 7)³ x 8 = 2³ x 8 = 8 x 8 = 64

(7² - 5²) + (5² - 3) = (49 - 25) + (25 - 3) = 24 + 22 = 46

6² : 2 - 14 x 5 = 36 : 2 - 14 x 5 = 18 - 14 x 5 = 18 - 70 = -52

3² x 2³ + 2² x 5² = 9 x 8 + 4 x 25 = 72 + 4 x 25 = 72 + 100 = 172

Bons estudos. :)
