Question

Determine o valor das expressões

Answer 1

Resposta:

37

a)

(1/4)*(3/2) -(8/27)  * (-27/1)

3/8 + 8

=3/8+64/8 =67/8

b)

(1/10)²/(-2) + (3/2) / (-1/10)²

(1/100)/(-2)  + (3/2) /(1/100)

(1/100)/(-2/1)  + (3/2) /(1/100)

(1/100) * (1-/2) + (3/2)*(100/1)

-1/200 + 300/2

-1/200+150

=-1/200 + 150*200/200

=-1/200 +30000/200 = 29999/200
