Question

Resolva as seguintes expressões numéricas:
a) 3² - 10 =
b) - 7 + (2⁴ + 1) =
c) (5 x 1³) - 20 =

Answer 1

a) 3² - 10 = 9 - 10 = -1

b) - 7 + (2⁴ + 1) = -7 + (16 + 1) = -7 + 17 = 10

c) (5 x 1³) - 20 = 5 - 20 = -15

Answer 2

a)

3² - 10 = 9 - 10 = - 1

b)

- 7 + (2⁴ + 1) = - 7 + (16 + 1) = - 7 + 17 = 10

c)

(5 × 1³) - 20 = (5 × 1) - 20 = 5 - 20 = - 15
