Answer 1

Resposta:

5.

a. {4/9 + (3/6)² . (∛27 - (+6) . (-3) + 2⁴)} =

{4/9 + (9/36) . (3 - (-18) + 16)} =

{4/9 + (9/36) . (3 + 18 + 16)} =

{4/9 + (9/36) . (37)} =

{4/9 + 333/36} =

{16/36 + 333/36} =

349/36

b. [3⁻² + (2/3)² - (√36/81 + 1/3 + 1/2)] =

[(3/1)⁻² + (4/9) - (6/9 + 1/3 + 1/6)] =

[(1/3)² + (4/9) - (12/18 + 6/18 + 3/18)] =

[(1/9) + (4/9) - (21/18)] =

[5/9 - 21/18] =

[10/18 - 21/18] =

-11/18
