​

Answer 1

Resposta:

a) 20-(1⁴-6+2³) =

20 - (1 - 6 + 8)

20 - (- 5 + 8)

20 - (3)

17

b) (2⁴-3•4) : 2+5² :5 =

(16 - 12) : 2 + 25 : 5

(4) : 2 + 5

2 + 5

7

c) 10² :5² +5⁰• 2²-2³ =

100 : 25 + 1 . 4 - 8

4 + 4 - 8

0

d) 6² + 2• [2³ + 2 •(3² •1³)]- 2⁵ • 5⁰ =

36 + 2 . [8 + 2 . (9)] - 32 . 1

38 . [90] - 32

3.338
